高陡倾倒蠕动滑移边坡变形破坏规律研究

Study on the rules of the deformation failure of high steep toppling-creeping slippage slope

通过对抚顺西露天矿北帮地质采矿背景与边坡变形特征的分析,研究了北帮倾倒蠕动滑移变形体变形破坏规律。研究认为,北帮倾倒蠕动滑移变形为由软弱夹层和反倾的地质结构体控制的一种特殊地质条件下的变形模式,其变形具有历时时间长、变形量大、破坏性强、变形影响范围广的特点。向斜核部开采,以及地下水位剧增促进了变形的快速发展。

This paper studies the deformation failure rules of the toppling-creeping slippage body of north-slope by the analyzing of the background of geology and mining and characters of deformation of north-slope in Fushun western surface mine. The results of the studies showed that the deformation of the toppling-creeping slippage of the north-slope is a deformation failure pattern under a special geology condition controlling by soft-weak interlining rock and geologic structure, the characters of deformation showed that it takes a long period of time and has big deformation values, strong destroying power and wide influence areas, tt hastened the development of deformation by mining on stones of syncline and suddenly rising water level.
