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

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.
