摘　　要：以江苏句容青龙山滑坡为例,通过对滑坡地质成因分析,找出影响滑坡的主要因素:断裂带及其影响带岩体结构松散,道路切坡形成陡峻的地形及连续强降雨。滑坡体南北两侧的断层及卸荷结构面构成滑坡体的纵向切割面,断层影响带的岩体因构造应力作用,牵引构造及结构面十分发育,为岩体的风化作用与地表入渗提供了十分有利的条件。滑坡体的滑动在断层影响带岩体于强降雨入渗条件下发生的楔形体破坏。Taking the Qinglongshan landslide in Jurong,Jiangsu as an example,through analyzing the geological genesis of the landslide,the main factors influencing the landslide were found:the fault zone and its influence zone had loose rock mass structure,and the road cut slope formed steep terrain and continuous heavy rainfall.The faults and unloading structural planes on the north and south sides of the landslide body constitute the longitudinal cutting plane of the landslide body.The rock mass in the fault-affected zone is well developed due to tectonic stress,and the traction structure and structural plane are well developed to provide weathering and surface infiltration of the rock mass.Very favorable conditions.The sliding of the landslide body is a wedge-shaped failure that occurs under the conditions of heavy rainfall and infiltration of the rock mass in the fault-affected zone.
