摘　　要：为减少高路堤边坡失稳对周边人民生命和财产安全的影响,以长三角地区某降雨型滑坡为研究对象,通过多源数据分析其成因和治理前稳定性,并据此展开滑坡综合治理工作,采用数值模拟和信息化监测对治理后边坡进行稳定性分析。结果表明:人类活动和强降雨是导致滑坡的主要原因;削坡减载和加锚杆等综合治理措施大大提高了边坡稳定性,使其在天然环境和暴雨环境下均处于稳定状态;信息化监测数据显示治理后边坡整体处于稳定状态,雨季边坡存在一定波动,必须加强该阶段变形监测预警工作。In order to reduce the influence of high embankment slope instability on people′s lives and property safety around the disaster area,a rainfall landslide in the Yangtze River Delta region is taken as the research object,and its genetic mechanism and stability before treatment are analyzed through multi-source data,and the comprehensive treatment of landslide is carried out accordingly.Finally,the stability of the slope after treatment is analyzed by numerical simulation and information monitoring.The results show that human activities and heavy rainfall in rainy season are the main causes of landslides.Comprehensive control measures such as cutting slope to reduce load and adding anchor bolt have greatly improved the stability of slope,and it is in a stable state in natural environment and rainstorm environment.The information monitoring data show that the whole slope is in a stable state after the completion of the slope treatment,and there are certain fluctuations in the slope during the rainy season,so it is necessary to strengthen the deformation monitoring and early warning work at this stage.
