断层与追踪破裂面构成不稳定块体的岩坡分析方法

【摘要】 本文探讨存在单一断层斜切岩石边坡时，断层与追踪破裂面所形成的三维块体的稳定性分析方法。分析表明，如果断层排水条件不好，或断层强度值比岩体低很多，则有可能发生由断层和横切岩体的某一追踪破裂面构成滑移楔体。可见，断层的水压作用是非常显著的，并以峨口铁矿山墙坪断层斜切南帮的稳定性分析为例。更多还原

【Abstract】 This paper discusses the possibility of the method of stability analysis of the rock slope with the wedge failure and intersected by a single fault and joints. The results show that the wedge failure is Possible if the groundwater condition is unfavourable or the strength of the fault is much lower than that of the rock mass. In this condition,the wedge is formed by existent fault and a potential joints roloase plane cutting through rock mass. An example appling this method to evaluate the stability of this kind of rock slope in E’kou open pit mine is presented.更多还原
