摘要
为了探究一种尽可能符合实际破坏模式的边坡三维稳定分析方法,提出了一种新的分析变形的方法.利用剩余推力法和优化原理建立边坡临界滑动场,实现危险滑动面搜寻和边坡稳定性评价;通过反分析方法,实现在给定安全系数条件下边坡坡角优化设计.编制了相应的计算分析软件,结合实际矿山工程进行具体计算,其结果符合工程实际,并对工程提出了优化设计方案.
A new method of deformational analysis was adopted to carry out the three-dimensional stability analysis of a slope so as to accord with the actual destruction pattern as possible. In the method, the residual thrust method and the principle of optimality were used to construct the critical slip field （CSF） of the slope, which not only is convenient to find out the arbitrary shape of critical slip surface, but also can be used in optimum design at a given safety factor by using the counter-analysis method. Corresponding software was compiled to calculate a mining engineering project, the calculation results agreed with the measured data, and some optimum design schemes were proposed for the engineering project
