APPLICATION RESEARCH ON NON-SIMULTANEOUS COUPLING CALCULATION OF DEFORMATION AND SEEPAGE WITH MANIFOLD METHOD AND FEM
流形元与有限元变形和渗流的非同步耦合分析方法及其应用

The calculation code including manifold method (MM) and finite element method (FEM) is developed to study the non-simultaneous coupling problem of stress-strain and seepage for discontinuous material. A simple rock slope model is used to simulate the failure development process of the rock blocks due to the action of water pressure change along rock fracture surface. The calculated result shows that the presented coupling analysis method is effective for the coupling problems of discontinuous rocks from small deformation to failure process.
