下滑坡及防治方案

Langxia landslide and its prevention cure scheme

下滑坡是由采煤引发的巨型深层顺层滑坡，目前处在蠕动变形阶段。本文对滑坡稳定性进行了计算，算出不同采空区面积下的稳定系数，计算了滑坡推力，提出了地表地下排水、煤层采空区设承重阻滑键、滑坡前缘设抗滑桩综合防治方案，可供防治设计施工参考。

The Langxia landslide is a giant scale deep seated along bedding landslide caused by coal mining,which is now in the creep deformation stage.In this paper,through the calculation of stability of the landslide,the stability coefficient of various mined out areas and the pushing force of landslide are calculated.A comprehensive prevention cure scheme including the surface and underground drainage,the installation of load bearing slide resisting key in mined out areas of coal beds and slide resisting piles in front of the slide site is put forward,which may be of reference value for the prevention cure design and construction.
