摘要
为寻求含软弱结构面的蠕动边坡稳定性控制因素及边坡失稳判据,为滑坡控制技术研究提供理论依据。对此类蠕动边坡变形力学系统模型进行了分析与讨论,结合各段的受力分析,得出此类边坡变形破坏的模式,为上部追踪节理、裂隙面形成准圆弧面,坡体在自重应力作用下,沿赋存有水平顺坡向或反坡向的缓倾软弱岩层蠕滑形成滑坡。此类滑坡控制应优先采用上部减重、下部压脚与边坡防排水工程相结合的综合治理方案。将此方案应用到安家岭露天矿北帮滑坡实例中,取得了良好的效果。
In order to find the controlling factors of slope stability and instability criterion for slope with weak structure plane,and provide a theoretical basis for developing landslide control technique,this paper reviews and analyses the mechanical system models for creeping slope.Also,based on the force analysis for each section,the paper concludes that the top part slip plane is a circular arc and the landslide mass slip follows the lower weak structure plane by gravity,which maybe bedding sub-horizontal structure or reverse structure.In order to manage this kind of landslide,the comprehensive measures should be taken：reducing the slope to decrease load;compacting slope foot to increase sliding resistance;water-proof and drainage system to increase the stability of slope.A case study at Anjialing open-pit mine shows the control plan works successfully.
