土坡稳定的优化分析

Optimum Analysis of Slope Stability

简单粘土边坡稳定分析的常用方法是条分法．该种方法需根据多次试算确定安全系数ｋ，计算工作量较大．本文将条分法中安全系数ｋ表示为滑动圆弧圆心坐标的函数，根据该函数的特点引入相庆的边界约束条件，由优化方法得到使ｋ为最小的圆心位置．根据该原理在微机上编制了计算程序，并通过算例进行验证．

Slice nethod is an essential method to analyse simple slope stablity. It usually calculates many times in oider to get the safety factor K. In this paper,it is expressed the faction of cir centre coordinates of slip circle. According to the faction, the restrain is made. By optimum theory, the minime K is obtained. The program is made in PC calculator. Using esamples the program is examined.
