岩质边坡滑移—弯曲破坏中间状态的工程地质分析

Engineering geological analysis on intermediate state before slide-bending failure for rock slope

通过对一个顺向坡实例的详细调查发现,顺向坡的滑移—弯曲破坏,在强烈弯曲—隆起之后、整体失稳之前还存在一个中间状态———碎裂—散体化。在对其形成条件进行初步分析的基础上,提出了“四阶段”的滑移—弯曲破坏地质力学模式。

Based on a detailed investigation on a consequent rock slope, it is found that a intermediate state of cataclastic-loosing before failure is there between the stages of both the strong bendlng-swell and the instability of rock body; for which a preliminary analysis is made on the forming condition, and then a geomechanical mode of ＂four stages＂ is put forward herein.
