摘要

针对FLAC3D面向复杂地质体与结构工程前处理建模存在的技术困难与不足，提出MIDAS/GTSFLAC3D耦合建模新方法。即先利用MIDAS/GTS进行三维几何建模和网格划分，然后，基于对两类软件中单元、节点数据关系的差异分析，应用MATLAB编写MIDAS/GTSFLAC3D接口程序，实现了MIDAS/GTS环境下建模的单元、节点信息导入FLAC3D的数据转换。通过下伏采空区矾水沟大桥师婆沟隧道复杂工程建模实例，验证了MIDAS/GTSFLAC3D耦合建模方法的可行性和有效性，为FLAC3D构建三维复杂工程模型提供了新的思路。

Abstract

A coupling modeling method with MIDAS/GTSFLAC3D was put forward aiming at the technical difficulties and deficiencies in preprocessing for complex geologic body and structural engineering with FLAC3D. The coupling procedure was that

firstly

the threedimension geometry model was built with MIDAS/GTS and the model meshes were divided. And Secondly

the element and node data of the completed model built in MIDAS/GTS were exported. After data was transformed by using the interface program in MATLAB

the information was imported into FLAC3D. Thus the threedimension FLAC3D model for complex engineering was generated coupling with MIDAS/GTS. With coupling method

the complex threedimension model was built for Fanshuigou bridgeShipogou tunnel engineering above minedout region

and the results verified the feasibility and effectiveness of the proposed method.
