基于刚体法和有限差分法的岩质边坡稳定分析

Stability Analysis of Rock Slope Based on Rigid Method and Finite Difference Method

用于岩质边坡稳定计算的刚体极限平衡法和数值分析计算方法各有优缺点，首先从计算理论和失稳判据两方面对比了Morgenstern-Price法和有限差分法，然后合理运用这两种方法对猴子岩料场边坡进行了二维计算分析，对比了两种方法的差异，对该边坡稳定性给出了判定，说明了综合应用刚体极限平衡法和数值分析计算方法进行岩质边坡稳定性分析评价的合理性和可行性。

Both rigid and numerical methods of calculations on the rock slope stability have advantages and disadvantages. Morgenstern-Price method and finite difference method are compared in theory and failure criteria in this paper, and the two methods are used to calculate and decide the stability of the material field of Houziyan Dam in the 2-dimentional analysis and to conduct a comparison on these two methods, predicating the stability of the rock slope, thus verifying the rationality and feasibility of comprehensively applying rigid and numerical methods to the analysis and evaluation of rock slope stability.
