中文摘要:
      老鹰湾滑坡体近年来一直存在滑坡隐患,影响西昌市大桥水库一期灌区工程的安全。根据工程勘查及调查,掌握了地 貌、变形、滑体、滑床、滑带等滑坡体基本特征,分析了滑坡形成机制,获得滑坡体岩土体物理力学参数。对最不利典型剖面,采 用简化Janbu法,对天然工况和暴雨工况下的滑坡体进行了稳定性计算和分析。研究表明:老鹰湾滑坡体属于牵引式滑坡体, 地形地貌、地下水活动、暴雨是主要诱因,易沿滑面产生滑动现象,建议迁出滑坡体上住户,同时加强对滑坡的监测预警。
英文摘要:
      There is a constant risk to the landslide-prone mass of Laoyingwan Slope in recent years, posing a threat to the security of the first-phase irrigation project of Daqiao Reservoir in Xichang City. Based on engineering surveys, we had better idea of the basic features of the mass's geomorphology, deformation, sliding section, sliding bed and sliding belt, analyzed the formation mechanism of landslide, and obtained physical and mechanical parameters of the sliding mass. Adopting simplified Janbu Method, we made stability calculations and analyses of the slide-prone mass under natural working conditions and heavy rain conditions. Our study shows: the landslide-prone mass of Laoyingwan Slope is of a tractive landslide type, formed mainly due to geomorphology, underground water action and heavy rain, which is liable to slide along the sliding surface. We suggest that residents on this sliding mass be relocated, and the work of monitoring and early warning of possible landslides be improved
