摘要
从地貌形态、古滑坡特征调查、滑坡发育的地质环境和滑坡变形监测分析,认为许家洞斜坡原来为一古滑坡;并基于此进行了滑带土抗剪强度的试验分析和滑坡稳定性对地下水位的敏感性分析,提出了滑坡治理设计的优选方案,经工程实践证明达到了降低工程造价和确保治理效果等目的,也可为类似滑坡的调查与治理提供参考.
Based on the analysis of geomorphologic features, site investigation of old-aged landslide features, geological environmental conditions for landslide developing and deformation monitoring to the landslide, Xujiadong slope is congnized to be an old-aged landslide. Optimum design is presented on the basis of the analysis of the slip soil shear strength characteristic and sensitivity of slope stability to underground water level. It is applied in engineering practice, and improve both the reducing engineering cost and the insuring purpose of landslide correction, can be a reference for the other landslide investigation and correction.
