目前一般在边坡稳定分析中计算方法较多,如瑞典法、毕晓普(Bihop)法、推力传递法、分块极限平衡法和詹布(Jandu)法等,以上诸法中的共同点均是在假定的滑裂面情况下求安全系数,并要假定多次,求其最小者。在计算中较麻烦,且有可能最危险滑裂面被“漏掉”等疵病。现试图用动态规划求安全系数K,并在求K过程中得到滑裂面形状。现将基本原理和方法介绍如下:
At present, there are many calculation methods commonly used in slope stability analysis, such as Swedish law, Bihop method, thrust transfer method, block limit equilibrium method, and Jandu method. The common points in these methods are In the case of a hypothetical slip plane, find the safety factor, and assume multiple times, find the smallest one. In the calculation, it is more troublesome, and there is a possibility that the most dangerous slip surface is “leaked” and other defects. Attempts to use the dynamic programming to find the safety factor K and obtain the shape of the sliding surface in the process of K. The basic principles and methods are now described as follows:
