摘要
目前针对采动滑坡的治理措施以抗滑桩等抗滑结构为主,而滑坡推力是抗滑桩研究中的热点问题。首先,从地下开采的影响效应、采动滑坡的破坏模式等方面对采动滑坡的研究现状进行了分析归纳,同时从理论研究和数值分析两方面总结了现有的采动滑坡稳定性分析方法。其次,对现有的两种主要滑坡推力计算方法(极限平衡法和数值计算方法)进行了总结梳理及对比分析,并指出了安全系数取值中存在的问题。再者,从理论分析、数值模拟、物理模型试验和现场监测等四个研究角度对滑坡推力分布进行了归纳总结。最后,在上述基础上提出对地下采动影响下滑坡推力的研究应从三个方向进行:采动滑坡推力的计算方法、推力分布形式和不同采动时期的滑坡推力变化情况。
        Currently the main control measures for mining landslide are still anti-sliding structures such as anti-slide piles,and landslide thrust is a hot issue in the study of anti-slide piles.First,the research status of mining landslide was analyzed and summarized from the effects of underground mining and the failure modes of mining landslide.Meanwhile,the existing analysis methods of mining landslide stability were summarized from theoretical research and numerical analysis.Second,the existing two main landslide thrust calculation methods(limit equilibrium method and numerical calculation method)were summarized and compared.And the problems in determining the value of safety factor was pointedout.Furthermore,the landslide thrust distribution was summarized from four perspectives:theoretical analysis,numerical simulation,physical model test and field monitoring.Finally,three directions of landslide thrust under mining landslide were proposed on the basis of above research:calculation method of mining landslide thrust,thrust distribution form and thrust variation in different mining periods.
