Abstract

From the current literature and some related practice, the rock mass disturbance was found having significant influence on evaluating rock slope stability, especially for the rock slope composed by poor quality rock masses. However the effect of this disturbance on the overall rock slope stability has not been thoroughly investigated. This paper adopts the limit equilibrium method (LEM) and the latest version of the Hoek-Brown failure criterion to investigate the rock mass disturbance effects on the rock slope stability evaluations. In addition, this paper considers a range of recommended damage zone thickness. Some stability charts will be proposed and potential influence zones are discussed.
