| 摘 要： | 本文根据工程岩体内存在宏观裂隙的特点,研究Autocad、Ansys联合建模技术.首先通过VB编程语言设计交互式随机裂隙面群的生成程序,并在Autocad中实现.其次,转入Ansys中进行系统模型设计.最后,在FLAC3D中进行数值模拟应用.从随机裂隙模型的应用效果来看,裂隙的存在使得岩体塑性范围加大,易失稳破坏.说明该方法生成的随机裂隙模型是可行的.

| Abstract: | In this paper,combining with the characteristic of macroscopical fissure in engineering rock mass,the authors study the modeling technology of random fissure by Autocad and Ansys.Firstly,the authors compile program of random fissure by VB,and realize the random fissure in Autocad.Secondly,the authors switch it to the model which Ansys could recognize,then design by the numbers in Ansys.Thirdly,the authors import the fissure model into FLAC3D for numerical simulation.According to the analog results,the plast... |
