Study on numerical simulation of faultage of seepage in underground project with latent complex-material element method

摘要: 结合地下工程渗流场三维有限元分析复杂性的实际,对断层的处理进行积极探讨。在拟连续介质模型的基础上,充分利用有限元法的特点,首次提出用隐式复合材料单元法对主要断层进行模拟。算例验证了该法的正确性和实用性。

Abstract: Combined with the complexity of 3D FEM analysis of seepage field of underground project,the simulation of faultage was comprehensively discussed.Based on the equivalent continuum model and the characteristics of FEM utilized,the method of latent complex-material element was firstly introduced to simulate the faultage.The correctness and practicability of this method was proved by an example.
