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.
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.
