某分级、分层、分区域破坏滑坡的稳定性分析及治理
摘要:以广东某复杂滑坡为典型工程案例，结合现场变形调查、工程地质调绘及补充深孔位移监测情况，对其进行分级、分层、分区，剖析其滑坡特征、产生滑坡的原因，认为地质环境、工程活动、降雨、地下水综合作用导致了边坡滑坡，最后针对该滑坡的特点及成因，提出分期、分区域治理，据此提出了竖向钢花管群桩+斜向预应力锚索冠梁的加固处治技术方案，可为类似地质条件下滑坡的处治思路提供参考。
Abstract:A complex landslide in Guangdong Province is analyzed as a typical engineering case. Combined with the field deformation survey, engineering geological mapping and supplementary deep hole displacement monitoring, the landslide is divided into different grades, layers and zones, and the landslide characteristics and causes are analyzed. It is considered that the comprehensive effects of geological environment, engineering activities, rainfall and groundwater lead to the slope landslide. According to the characteristics of the landslide, the technical scheme of "vertical steel pipe group piles + inclined prestressed anchor cable crown beam" is put forward, which can provide reference for the treatment of landslide under similar geological conditions.
