中文摘要: 针对复杂地貌和地质构造条件下数值模拟的建模问题,基于FLAC3D平台提出了从局部到整体的建模思想,采用Brick单元和Tetrahedron单元通过编程生成复杂地貌条件下的三维地质体模型。利用趋势面分析法拟合出层状连续地质体,将其定义为不同的"群",建立了多层状三维地质体结构模型。采用interface界面模拟出了断层面,并与趋势面相结合,构建了断层上下盘中的地层。认为通过数学分析结合计算机编程,可以实现直接在FLAC3D中进行复杂地貌和地质构造条件下的地质体建模。

Abstract: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.
