基于獨(dú)立覆蓋流形方法與矢量和方法的邊坡穩(wěn)定性分析
[Abstract]:A slope stability analysis method based on independent covering manifold method (independent cover manifold method,ICMM) and vector sum method is proposed. In this method, ICMM is used to calculate the stress field of slope rock and soil, which avoids the complex pretreatment process of finite element method and traditional manifolds method, and can conveniently calculate the stress state of complex slope with discontinuity surface such as joint fault. On this basis, the vector sum method is used to calculate the safety factor of the potential slip surface. The vector and method are based on the real stress state of the slope and the vector characteristics of the force, the physical meaning is clear, and there is no need for iterative calculation similar to the strength reduction method. The calculation cost is small. At the same time, simulated annealing genetic algorithm is used to optimize the search, and the critical slip surface of the slope is obtained. Combined with the above advantages, the method can calculate the critical slip surface and safety factor of complex slope with joint fault efficiently and accurately. The effectiveness and accuracy of the proposed method are verified by the analysis and application of four representative examples and engineering cases.
