REFINED MODEL ING OF 3D GEOLOGICAL BODY BASED ON REVERSE ENGINEERING AND THE APPL ICATION OF AD INA IN THE MODEL BUILD ING OF FLAC3D

Reverse Engineering, as a new discip line, has unique advantages in comp lex modeling. It has been widely used in many fields. This paper firstly uses the reverse engineering technique to build the refined modeling of a comp lex geological body. The established model is viewable and computable. As the universal finite element simulation system, such as ABAQUS, AD INA and ANSYS have a good function in mesh generation and have a good interface with many CAD /CAM software systems. Using the method, geometrical body ismeshed in FEM system, then the mesh can be translated into the format that can be received by FLAC3D. By this, the comp lex geology body can be built in FLAC3D , and the p re - p rocess shortage of FLAC3D can be overcame. For this purpose, an interface p rogram between AND INA and FLAC3D is developed, and the methods are expounded. Above techniques are used in an engineering p roject. The results are validated.
