摘要
为研究近坝库岸滑坡堆积体对水库建筑物及附近居民安全的影响,采用基于极限平衡理论的传递系数法,查明重庆市向阳水库工程滑坡堆积体的稳定边界条件,对自重、自重+度汛水位由386 m降至367.24 m、自重+度汛水位由386 m降至367.24 m并叠加暴雨等3种工况下滑坡体的稳定性进行分析与评价。结果表明:该滑坡在3种工况下处于基本稳定、欠稳定和不稳定状态,结果与现场实地调查情况一致,建议采取工程治理措施。
To study the influence of reservoir bank landslide deposit near the dam on the safety of reservoir buildings and residents nearby,we used the transfer coefficient method based on the limit equilibrium theory,identified stable boundary conditions of the landslide deposit of Xiangyang Reservoir in Chongqing City.The stability of the landslide deposit was analyzed and evaluated under three working conditions,namely,the dead-weight,dead-weight+flood control water level from 386 m to 367.24 m,dead-weight+the flood control water level from 386 m to 367.24 m accompanied by rainstorm.The result showed that the landslide was basically in stable,under-stable and unstable state in three different conditions,respectively.The results were consistent with the actual investigation and engineering measures were recommended.
