摘要
针对东北抚顺西露天矿复杂的地质条件,利用物理模拟方法对岩体开挖、边坡形成过程进行相似模拟,并对全场边坡岩体位移变化跟踪观测。通过对该露天矿在边坡在开采扰动过程中的位移变形进行统计和分析,可较全面地给出边坡岩体在开挖过程中的位移变化规律,基本掌握该露天矿边坡变形破坏模式及其产生的主要原因,从而得出地质构造对边坡破坏的影响模式。
The processes of rock excavation and slope formation of open-pit mine are simulated by physical simulation aimed at complicated geological conditions strip mine,and the displacements movement of rock mass are observed ever and again in this paper.The displacements and deformation caused by excavation are observed and analyzed;and the displacement laws of slope rock mass are gained during the disturbance process.Furthermore,the mode of the slope breakage is held by and large,the dynamic characters and the primary causation of the slope are discussed.The influence mode of slope breakage by geological structure is educed.The model of idiographic engineering geology is put forward for the open-pit mine.
