在Midascivil模型里批量添加桩基土弹簧

在用midascivil做计算的时候，有些模型需要建立桩基础来考虑桩土效应，手动添加土弹簧是一件很繁琐的事情。为提高工作效率，基于python写了一个脚本，能直接把excel表格计算的土弹簧批量地添加到midas模型里面。

Python程序代码

运行脚本后会生成一个mct脚本文件，在midascivil软件的mct命令窗口打开，然后运行就可以了，需要先计算好土弹簧参数放入相应的excel表格，代码部分土弹簧参数根据自己使用的midas版本进行调整。代码如下：

import pandas as pd
import subprocess

def run_midas_script(script_path):
    subprocess.run(['midas_civil_path', '-run', script_path], check=True)

def generate_midas_script(df, output_script_path):
    with open(output_script_path, 'w') as f:
        for index, row in df.iterrows():
            node_id = row['NodeID']
            stiffness_x = row['SpringStiffnessX']
            stiffness_y = row['SpringStiffnessY']
            stiffness_z = row['SpringStiffnessZ']
            
            command = f"""
            *SPRING
            {node_id}, LINEAR,NO, NO, NO, NO, NO, NO, {stiffness_x}, {stiffness_y}, {stiffness_z}, 0, 0, 0, NO, 0, 0, 0, 0, 0, 0, 边界组, 0, 0, 0, 0, 0
            """
            f.write(command)

def main():
    excel_file = 'soil_spring_data.xlsx'
    output_script_path = 'add_soil_springs.mct'
    
    df = pd.read_excel(excel_file)
    generate_midas_script(df, output_script_path)
    run_midas_script(output_script_path)

if __name__ == "__main__":
    main()

excel表格土弹簧数据

导入mct脚本运行后结果
