| Abstract: | With the high rock slope as the research objective,a large-scale and meticulous finite element model is established that can well reflect the relationship between the internal block and structural plane mainly as viewed from the safety factors,the rock slope behaviors and the accuracy of structural surface mechanical parameters are analyzed quantitatively.The simulation back analysis of rigid limit equilibrium method is carried out in terms of the results of parameter sensitivity analysis,whereby obtaining the quantitative evaluation of slope sability of FEM. |
