摘要

根据极限平衡法基本假定和圆弧滑动机理

使用条分法中的径向条分模式

将滑动土体径向条分

结合径向条分特点对土条进行受力分析

求得一种新的土质边坡稳定安全系数迭代计算公式

最终得到新的边坡稳定性分析与计算方法——向心条分法。算例分析表明:向心条分法边坡稳定安全系数计算公式迭代收敛稳定快速

计算结果以及最危险滑动面与以往研究成果非常接近

可证明向心条分法的正确性;同时

分析了条间法向力作用位置对计算结果的影响

证明了条间法向力作用位置为土条侧边的下三分点处这一假定条件的合理性。

Abstract

With radial slice method

based on the primary assumptions of limit equilibrium method and the mechanism of circular sliding

combining features of radial slice method

the mechanical analysis is conduced to derive a new iterative computational formula of factor of safety（FOS）of soil slope stability

and a new slice method

arc-to-center slice method

is obtained.Based on this method

aprogram is made in FORTRAN language.Through analyzing examples

it shows that the convergence of iterative computation of arc-to-center slice method is fast and stable and both the minimum FOS and critical sliding surface are close to the results of existing methods

which shows the correctness of arc-to-center slice method.Secondly

the influence of the position of normal force between slices on the results of computation is analyzed

which shows the rationality of the assumption that the position of the normal force between slices is at one third of the length of the slice side.
