摘要
通过对牵引式中型中层滑坡现场工程地质条件系统地调查,对其坡体结构及变形破坏特征进行细致的研究,在此基础上,对该堆积体的复活机制进行详细的分析。以此为依据,通过定性分析和定量计算对该滑坡进行稳定性评价,综合判定滑坡体在天然工况下处于基本稳定状态,在持续暴雨等不利工况下处于欠稳定状态。基于以上认识,提出了"抗滑桩+地表截排水+专项监测"的综合治理方案对该复活体进行治理,同时为同类堆积体复活机制的分析和工程治理提供一定的参考。
Through the survey to the geological condition system in the traction type medium middle-level loose talus landslide site construction,we have made a meticulous research to the slope structure and deformation failure characteristics.On this basis,we give a stability evaluation to this slope by qualitative and quantitative analysis.The summary is that the landslide is nearly in stable state under natural conditions,and in unstable state under the continuous rain and some other adverse conditions.Based on the above understanding,we put forward a comprehensive management programme on the resurrection body management as 'antislide+surface drainage+special monitoring'.At the same time,this paper will provide a reference to the resurrection mechanism analysis and comprehensive management among similar accumulation bodies.
