摘　　要：介绍了通用条分法(GLE)的基本方程,通过定义不同条间力倾角函数,可以方便的模拟各种简化条分法和严格条分法,如简化Bishop,简化Janbu,Spencer法,Morgenstern-Price法等。采用该方法对广州一土岩混合高边坡几种可能的滑动破坏形式进行稳定性分析,并对加固设计进行验算。分析表明采用的设计加固方案能够满足稳定性要求。The basic equations of generalized limit equilibrium method （GLE） are introduced, through defined function of different interslice force angles, GLE can simulate rigorous methods such as Spencer and Morgenstem-Price methods, as well as other simplified methods such as Bishop and Janbu methods. GLE method is applied to analyze the stability of soil-rock composite high slope in Guangzhou city. The failure may occur in the soil with a circular slip or between the soil and the rock with a composite slip. The two failure forms are both considered in the stability analysis before and after reinforcement. The result of checking calculation of reiforeement design shows the reinforcement design scheme can satisfy the requirement of stability.
