摘　　要：通过对边坡岩性、结构构造、地质环境及变形破坏形迹等工程地质分析，揭露出边坡变形破坏的形成机理和地质力学模式是由构造结构面形成变形体切割面，采矿开挖使边坡临空及爆破与震动等影响而形成的。通过变形变迹分析，判断得出该边坡变形处于滑移面贯通阶段，并有形成加速下滑，导致滑坡的趋势，为后期定量评价边坡稳定性和制订整治方案提供依据。Through the engineering geological analysis of slope rock properties, texture and structure, geological environment and movements and expressions of formation failure, the formation mechanism and geo - mechanical mode of the slope formation failure are exposed. It is structural and textural face that forms the cutting face when it is affected by the emptied slope due to mining extraction , blasting and vibration. Though the analysis of the deformation movement and expression and by judgment, it is concluded that the deformation of this slope is at the stage of sliding face penetration and there is a tendency of sliding acceleration and landslide formation , thus providing the basis for the evaluation of the slope stability in the later period and for laying down the control scheme.
