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。
In this paper, we discuss the stability analysis of 3D block formed by fault and tracing rupture in the presence of a single fault slope. The analysis shows that if the fault drainage conditions are not good or the fault strength is much lower than that of the rock mass, it is possible that a slip wedge may be formed by a tracing rupture of the fault and the transversal rock mass. It can be seen that the hydrodynamic pressure of the fault is very significant, taking the stability analysis of the south slope of the Miaoping fault in Ekou iron mine as an example.
