高密集片理结构千枚岩边坡变形特性研究

On the Deformation Characteristics of Dense Schistose Phyllite Slope

摘要: 以某露天采场边坡为例，结合现场勘察，对高密集片理结构千枚岩边坡的变形特性进行了分析，揭示了该类边坡岩体的失稳模式，并综合分析了该边坡的变形破坏机制及发展趋势.研究结果表明，该类边坡岩体具有多种失稳方式，其中以局部的弯曲折断破坏为主，并在一定条件下，可能朝着蠕滑—拉裂的破坏方式发展.

Abstract: Illustrated by the case of slope in an open pit mine, a lot of facts from field investigations showed the deformation model of dense schistose phyllite slope. The results show that: the major form is bending and breaking in multi-mode damage of slope. Accompanied with this process, a potential slip surface develops gradually in the slope.
