采用广义Hoek-Brown准则反算滑坡岩体强度

摘要

A sliding slope can be served as f full-scale test of rock mass strength,which reflects the characteristics that slope rock mass responses to mechanics under specifed geologic and engineering conditions.This paper proposes a brief and practical method for estimating the shear strength parameters mobilized during slope failure in cataclast texture rock mass using back analysis procedure from the generalized Hoek-brown non-linear failure criterion into which the geological stength index (GSI) is introduced.%滑坡可能为一个实比例的大型岩体强度“试验”，它真实地反映特定地质和工程条件下边坡岩体的力学响应特性。本文采用非线性广义Hoek-Brown破坏准则，引入地质强度指标，为反算碎裂结构岩体边坡破坏时所调动的抗剪强度参数提出一种简洁、实用的方法。
