  • With respect to the problem of numerical modeling for simulation in conditions of complex lan dforms and geological structure, the idea of modeling from the part to whole was put forward based on the FLAC3D platform.Using the primitive mesh shapes of brick and tetrahedron, a 3D model of the geologic body under complex landform conditions was constructed by means of computer programming.A lay ered continuous geological body was fitted up using the trend surface analysis and defined as different "groups".Thus a multi-layered 3D structure model of the geologic body was constructed.The fault plane in the geologic body was simulated by using interface.On that basis, combined with the trend surface analysis, the strata of the hanging wall and footwall of a fault were simulated.The authors consider that a 3D model of the geologic body with complex landforms and geological structure can be constructed in FLAC3D directly by using mathematical analysis and computer programming.
