基于HYPERMESH复杂地质体的FLAC3D实体建模
Modeling of Complex Geological Body in FLAC3D Based on HYPERMESH
摘要
Abstract
FLAC3D use explicit finite difference method to solve the differential equation,which has an obvious advantage over other methods in numerical analysis of civil engineering.But there is a shortage in FLAC3D to build three-dimensional geological model.Combining AUTOCAD with HYPERMESH software,complicated geological model was built.Making full use of the advantages of HYPERMESH in dividing mesh,developing mesh quality and checking the continuity of grids,preliminary treatment of model was made.An interface program of HYPERMESH-TO-FLAC3D was programed to import complex model into FLAC3D analysis.All these help to carry out the purpose of building the model more quickly and accurately.This method was checked viably and effectively by a 3D model example of underground cavern groups in Wudongde hydropower station.The results show that this method can develop the efficiency of building model greatly; and it can be very practical in building model by FLAC3D.关键词
