In the case of the example, the road embankment is executed). Then, the details of the superstructure (in this example, the height of the road embankment, the height of the ceiling, etc.) are displayed through an input / output interface screen as shown in FIG. End width, etc.).

When the information on the planned construction site and the superstructure to be constructed is input by the processing of S301 and S302, the ground modeling processing unit 112 extracts the ground design constant at the planned construction site (S303). On the other hand, the superstructure modeling processing unit 113 performs primary processing on information relating to the superstructure and models the superstructure (S30).

Although the importance parameter is input after the processing of Steps 5 to S316 is completed, the importance parameter may be input together with the information on the planned construction site and the superstructure.

When the importance parameter is input, the ground improvement method extraction unit 116 first determines the presence or absence of the settlement countermeasure flag, the stability countermeasure flag, the bearing capacity countermeasure flag, and the liquefaction countermeasure flag, and determines the presence or absence of the flag. The ground improvement method corresponding to the flag is extracted from the ground improvement method database 105 by reference.

Then, when several ground improvement methods are extracted, the importance parameter (a) input by the user is substituted into the expression shown in the lower part of FIG. 8, and the score value of each method is calculated (S318). In this case, a score (X) is given to each method in advance for economy (= construction cost), construction environment (= vibration / noise / ground displacement), construction period, and reliability (= actual) of the method. The score (X) is weighted based on the importance parameter specified by the user, and the comprehensive evaluation of each method is output. FIG.

If the method is a method corresponding to a plurality of countermeasures because it is a relative evaluation value with another method, the correction is made so that the maximum evaluation value is 100. Here, this correction process may be calculated in advance for each combination of measures, or may be calculated when extracting a method of construction, or may be any method.

When the ground improvement method corresponding to the flag calculated as described above is extracted, the ground improvement method extraction unit 1
16 prompts the user to input the importance parameter (a) for the construction cost, the construction environment, the construction period, and the performance. Then, when the importance parameter (a) is input (in this example, 0.3, 0.5, 0.1, 0.
1) The ground improvement method extraction unit 116 inputs the value of the importance parameter (a) into the above-described equation shown in the lower part of FIG.
Outputs the total evaluation value of each construction method from the aspects of construction environment, construction period and actual results. In the case where there is no input of the importance parameter, the ground improvement method extraction unit 116 outputs the comprehensive evaluation value of each method by equalizing the importance parameters for the construction cost, the construction environment, the construction period, and the results. .

When the comprehensive evaluation value of each site improvement method is output, the soil improvement method extraction unit 116 determines the soil improvement method having the highest overall evaluation value as the optimum soil improvement method for the planned construction site and the superstructure where the user has input. The output is output to the output unit 102 (S319). More specifically, the ground improvement process can be started based on the output information.
Outputs information about the extracted ground improvement method, such as the outline, characteristics, applicable ground, construction results, applied depth, environmental aspects, and reliability. Then, the user executes the ground improvement process using the information regarding the optimum ground improvement method output via the output unit 102 (S320). Here, for example, the user is disclosed in Japanese Patent No. 2584402 and Japanese Patent No. 18584.
The ground improvement processing can be started promptly with reference to the technical information on the ground improvement method shown in Japanese Patent No. 38688 or the like, and the ground improvement processing can be performed more efficiently.

Here, the information on the ground improvement method to be output may be one ground improvement method having the highest evaluation value, or a plurality of information may be output in the order of the evaluation value.
When a plurality of output values are output in the order of evaluation values, it is desirable to display the details in a stepwise manner according to the user's selection.
