The evaluation support device for solving the above problem includes an input sheet storage unit that records information entered in a spreadsheet file, and a control unit connected to a modeling device that generates a three-dimensional model. The control unit acquires a spreadsheet file with input fields for geological layer information included in a ground investigation report, records the file in the input sheet storage unit, converts the geological layer information included in the spreadsheet file into information that can be input into the modeling device, and inputs the information. The control unit then acquires and outputs a three-dimensional geological layer estimation model generated based on the geological layer information from the modeling device.

This disclosure can assist in the evaluation of ground through efficient 3D modeling of geological information.

(Support processing)
The support process will be described with reference to FIGS.
As shown in FIG. 5 , the control unit 11 of the evaluation support device 10 executes an input process for the range to be modeled (step S01). Specifically, first, a spreadsheet application program is launched. Then, the support processing unit 111 of the control unit 11 outputs a template spreadsheet file 120 to the display device H13. This spreadsheet file 120 includes an investigation position sheet 121 through an earth retaining wall sheet 127, with each item left blank. In this case, the model name, model lower limit elevation, model creation range, number of grid divisions, and plan view image file name are input in the investigation position sheet 121. In this case, the support processing unit 111 of the control unit 11 records the spreadsheet file 120 in the input sheet storage unit 12.

For example, as shown in FIG. 6, the model creation range 510 is set by referencing the floor plan 500 corresponding to the structural design floor plan specified by the floor plan image file name on the survey position sheet 121. In the modeling device 20, this model creation range 510 is divided into the specified number of grid divisions.

Next, the control unit 11 of the evaluation support device 10 executes a process for inputting stratum type information (step S02). Specifically, the stratum ID, stratum classification, color, attributes, etc. are input for each stratum classification in the current ground in the stratum classification name sheet 122. In this case, the support processing unit 111 of the control unit 11 updates the stratum classification name sheet 122 in the spreadsheet file 120 recorded in the input sheet storage unit 12.

Next, the control unit 11 of the evaluation support device 10 executes a process for inputting borehole information (step S03). Specifically, for each borehole, information such as the borehole ID, hole mouth elevation, location coordinates, minimum depth, soil classification, stratum ID, and standard penetration test results is input into the log sheet 124. In this case, the support processing unit 111 of the control unit 11 sets the stratum classification corresponding to the input stratum ID from the stratum classification name sheet 122 on the log sheet 124. The support processing unit 111 then updates the log sheet 124 of the spreadsheet file 120 recorded in the input sheet storage unit 12.

Next, the control unit 11 of the evaluation support device 10 executes a process for inputting cross-section line coordinates (step S04). Specifically, information regarding the cross-section line ID, cross-section coordinates, etc. for identifying the desired cross-section is input into the cross-section sheet 125. In this case, the support processing unit 111 of the control unit 11 updates the cross-section sheet 125 of the spreadsheet file 120 recorded in the input sheet storage unit 12.

For example, as shown in Figure 6, for one section line ID, cross-sectional coordinates c1, c2, and c3 are set in order for multiple nodes in the floor plan 500. Also, for another section line ID, cross-sectional coordinates c4, c5, and c6 are set in order for multiple nodes.

Next, the control unit 11 of the evaluation support device 10 executes input processing for pile information and retaining wall information (step S05). Specifically, information such as the pile ID, pile diameter, pile top height, pile length, and coordinates is input into the pile sheet 126. Also, information such as the retaining wall ID, coordinates, top height, and length is input into the retaining wall sheet 127. In this case, the support processing unit 111 of the control unit 11 updates the pile sheet 126 and the retaining wall sheet 127 in the spreadsheet file 120 recorded in the input sheet storage unit 12.

Next, the control unit 11 of the evaluation support device 10 executes a conversion process (step S06). Specifically, the interface unit 112 of the control unit 11 converts the information on each sheet of the spreadsheet file 120 recorded in the input sheet storage unit 12 into a format compatible with the modeling device 20. The interface unit 112 then inputs the converted information into the modeling device 20.

Next, the modeling device 20 executes a process for generating a geological layer model (step S07). In this case, the modeling unit 21 generates a 3D model of each layer based on the information acquired from the interface unit 112. Specifically, the modeling unit 21 first generates a cylindrical 3D model for each borehole position coordinate. Next, the modeling unit 21 positions the layers using the minimum depth of each layer relative to the borehole position coordinate. Next, the modeling unit 21 estimates layer boundary surfaces in the adjacent cylindrical 3D models so as to connect common layers. In this case, the layer surfaces are smoothed using an approximation method. The modeling unit 21 then records a 3D model (layer estimation model) in which the estimated layer boundary surfaces are set in the model information storage unit 22. Furthermore, the modeling unit 21 generates pile models and earth retaining wall models based on the information recorded on the pile sheet 126 and earth retaining wall sheet 127, and records these in the model information storage unit 22.

Next, the control unit 11 of the evaluation support device 10 executes a process for outputting the 3D model (step S08). Specifically, the viewer unit 113 of the control unit 11 acquires the geological formation estimation model recorded in the model information storage unit 22. The viewer unit 113 then outputs the display screen 600 to the display device H13.

In this case, as shown in Figure 7, a geological formation estimation model 601 for each layer is output in a three-dimensional virtual space on the display screen 600. In addition, cross-sectional lines 602 and 603 are displayed on the ground surface. Cross-sectional line 602 is specified by cross-sectional coordinates c1, c2, and c3. Cross-sectional line 603 is specified by cross-sectional coordinates c4, c5, and c6.

When a cross-section display is instructed, the viewer unit 113 instructs creation of a cross-section using the geological formation estimation model recorded in the model information storage unit 22 .
8, the viewer unit 113 acquires a display screen 610 including a cross-sectional view from the modeling device 20. Cross sections 612 and 613 corresponding to the cross-sectional lines 602 and 603 in the geological formation estimation model are displayed on the display screen 610.

When the display of the supporting layer is instructed, the viewer unit 113 identifies a supporting layer whose N value exceeds a reference value in the stratum estimation model recorded in the model information storage unit 22. The user may specify a stratum to be regarded as the supporting layer. In this case, the viewer unit 113 identifies the specified stratum as the supporting layer.
9 , the viewer unit 113 acquires a display screen 620 including the support layer, the borehole, and the pile from the modeling device 20. This display screen 620 includes a support layer model 621, a borehole model 622, and a pile model 623.

When an instruction to display the retaining wall is given, the viewer unit 113 generates the retaining wall model recorded in the model information storage unit 22 .
10, the viewer unit 113 acquires a display screen 630 including the retaining wall from the modeling device 20. This display screen 630 includes an earth retaining wall model 631.

Next, the control unit 11 of the evaluation support device 10 executes a process for displaying a cross-sectional view (step S09). Specifically, the support processing unit 111 of the control unit 11 outputs a cross-sectional view selection screen. On this cross-sectional view selection screen, multiple borehole IDs are specified. In this case, the support processing unit 111 generates a cross-section whose upper edge is a straight line connecting the coordinates of each borehole location. The support processing unit 111 then outputs a cross-sectional view of the geological formation estimation model cut out at the generated cross-section.

As shown in Figure 11, when cross-sectional display is instructed, display screen 640 is output. This display screen 620 displays a cross-sectional view of the strata corresponding to drilling positions 641 to 645. In addition, standard penetration test results (N values) are displayed at each drilling position 641 to 645.

Next, the control unit 11 of the evaluation support device 10 executes a process for checking the stratum boundary surface (step S10). Specifically, the support processing unit 111 of the control unit 11 acquires the lower limit depth for each stratum recorded on the log sheet 124 for each borehole position coordinate.
In this case, as shown in FIG. 12, an actual measurement table 651 is generated in which the minimum depth is recorded for each boring position coordinate and each stratum.

Next, the support processing unit 111 calculates the estimated lower limit depth of the stratum at the borehole position coordinates in the stratum estimation model recorded in the model information storage unit 22. In this case, as shown in Figure 12, an estimation table 652 is generated that records the estimated lower limit depth for each borehole position coordinate and each stratum.

Then, the support processing unit 111 calculates the difference between the minimum depth in the actual measurement table 651 and the estimated minimum depth in the estimation table 652 for each stratum at each borehole location coordinate. If the difference exceeds the elevation difference threshold, the support processing unit 111 outputs a warning message. This warning message includes information that can identify the borehole location coordinates and the stratum.

The support processing unit 111 also calculates the gradient in the depth direction in the shape of the stratum boundary surface of the three-dimensional model recorded in the model information storage unit 22 .
As shown in Figure 13, a stratum boundary surface 66L is estimated at the borehole position coordinates 661 to 666 according to the depth of the common stratum ST1. Note that while Figure 13 shows the stratum boundary surface 66L as a line, in three-dimensional space it becomes a two-dimensional surface. Next, the support processing unit 111 calculates the gradient SL1 at each position of the stratum boundary surface 66L. If the calculated gradient exceeds a gradient threshold (e.g., 60 degrees), the support processing unit 111 outputs a warning message about the gradient of the stratum. The warning message includes information that can identify the stratum and area that exceeds the gradient threshold.

Next, the control unit 11 of the evaluation support device 10 executes pile length evaluation processing (step S11). Specifically, the viewer unit 113 of the control unit 11 identifies the upper and lower sides of the support layer in the pile model. The viewer unit 113 then generates a display screen that allows the upper and lower sides of the support layer to be distinguished.

As shown in Figure 14, when a pile display command is issued, a display screen 670 is output. This display screen 670 displays a pile model 671 in three-dimensional space. In this case, the pile model 671 is displayed with the upper side p1 and lower side p2 of the supporting layer displayed in different colors. The user can also create a stratum consisting of two layers: a supporting layer and the layer above it. In this case, the upper side p1 and lower side p2 of the supporting layer are displayed in different colors using a function that displays the color of the layer that intersects with the pile.

Furthermore, as shown in FIG. 15, when a pile length adjustment display is instructed, a display screen 680 is output. This display screen 680 also displays a pile model 681 in three-dimensional space. In this case, the upper side p1 and lower side p3 of the support layer are displayed in different colors in the pile model 681. Here, the lower side p3 is adjusted to a predetermined length within the support layer. That is, if the pile does not reach the support layer, the pile length is increased so that it reaches the predetermined length within the support layer. On the other hand, if the pile is too deep below the support layer, it is decreased so that it reaches the predetermined length within the support layer. As a result, the sum of the length of the upper side p1 and the length of the lower side p3 becomes the pile length required for each pile model 681. Note that the user may check the display screen 670 and re-input the length of the lower side p3 of the support layer.

According to this embodiment, the following effects can be obtained.
(1) In this embodiment, the spreadsheet file 120 includes a survey location sheet 121, a stratum classification name sheet 122, a ground surface survey sheet 123, a columnar diagram sheet 124, a cross-sectional diagram sheet 125, a pile sheet 126, and an earth retaining wall sheet 127.

This allows the validity of the stratum estimation model to be confirmed. Here, the support processing unit 111 outputs a warning message if the difference exceeds the elevation difference threshold. This allows the discrepancy between the estimated stratum depth and the actual measured value to be confirmed. Furthermore, if the calculated gradient exceeds a gradient threshold (e.g., 60 degrees), the support processing unit 111 outputs a warning message regarding the gradient of this stratum. This allows the stratum with an unusual shape to be confirmed.
