摘　　要：倾倒破坏是岩质边坡主要失稳类型之一,极限平衡分析仍是目前最为常用的一种方法。基于Goodman和Bray提出的分析岩石边坡倾倒破坏的极限平衡方法,通过矢量运算计算倾倒稳定安全系数,编制了相应计算程序,并结合算例进行验证。算例结果表明:该方法计算结果合理,可应用于边坡工程设计。Toppling failure is one of the main types in rock slope failure and limit equilibrium analysis is still the most commonly used method at present.Based on toppling failure limit equilibrium method put forward by Goodman and Bray,safety factor of toppling stability is calculated by vector operation,corresponding calculation program is compiled and verified through calculation example.The result shows that the calculation results of the method are reasonable and can be applied to slope engineering design.
