摘要
以岩质高边坡为研究对象,建立能够反应边坡内部块体、结构面之间关系的大型、精细有限元模型。主要从安全系数角度出发,量化分析边坡岩性和结构面力学参数的准确性,根据参数敏感性分析结果进行刚体极限平衡法仿真反演分析,从而得到边坡稳定性有限元分析的定性评价。
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 quan- titative evaluation of slope sability of FEM.
