摘要
提出了一个用流形元与有限元的变形和渗流非同步耦合的分析方法,用于模拟不连续块体在水压作用下的变形过程。对一个岩石边坡上的裂隙岩块随地下水上升而产生滑动破坏的过程进行了计算模拟,将此数值计算结果与岩块的滑动极限平衡计算结果作了比较分析。计算结果显示了所提方法的可用性。
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.
