The stability analysis of the slope is a redundant problem. To statically determinate, within the frame work of limit equilibrium methods of stability analysis, no restriction need be placed at the outset upon the shape of the possible slip surface. It is necessary. The repetition calculation are necessary to get the results.This analysis is assumed the inner stress tau_r, tau_y change according to linearly equation which are satisfied the boundary condition. The principal stress sigma_1, sigma_2 and the shear stress tau are divided form tau_1 and tau_1. From the sigma_1, the shear resistance tau_f are introduced by the sigma1 tan phi. The instability zone are divided by tau > tau_f. The analysis results are checked by the experimental observation data. The analysis results conform well to the observation results.

边坡的稳定性分析是一个多余的问题。为了静态确定，在稳定性分析的极限平衡方法的框架内，不需要从一开始就对可能的滑移面的形状施加限制。有必要。需要重复计算才能得到结果。本分析假设内应力tau_r、tau_y按线性方程变化，满足边界条件。主应力 sigma_1、sigma_2 和剪应力 tau 分为 tau_1 和 tau_1。从 sigma_1 中，剪切阻力 tau_f 由 sigma1 tan phi 引入。不稳定区由 tau > tau_f 划分。分析结果通过实验观测数据进行检验。分析结果与观测结果吻合较好。
