摘要

为了探讨强度折减计算边坡稳定性过程中安全系数和滑动面之间的关系，针对一均质边坡算例，通过理论分析和FLAC3D强度折减法数值计算，分析当黏聚力和内摩擦角变化时，边坡安全系数和滑动面位置的响应情况，结果表明：(1) 边坡的安全系数受到黏聚力或内摩擦角中任一值的影响，而滑动面位置受到两者组成的函数（）的影响；(2) 当为定值时，改变抗剪强度参数和并不能引起滑动面位置的变化；当增大时，边坡破坏模式由浅层破坏转变为深层破坏，滑动面越来越缓，其上缘逐渐远离坡顶，滑体的体积增大。

Abstract

In order to study the relationship between safety factor of slope and its slip plane during the slope stability calculation by strength reduction method

the theoretical deduction and numerical calculation of strength reduction method by FLAC3D are done. The safety factor and location of slip plane for slope are analyzed for a homogeneous slope with the variation of cohesion and friction angle . The analysis results show that (1) the safety factor of slope is influenced by anyone of cohesion and friction angle

but the location of slip plane is instead influenced by the combination function of c and φ

which has the formula of

where is the height of slope; (2) when equals to a constant

the locations of slip plane will not change by the variation of shear parameters and ; with the increase of

the failure mode of slope changes from shallow slippage to deep slippage

the slip plane becomes more and more smooth while the top of it moves farther away from the vertex of slope

and slipping volume becomes greater.
