  • 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.
