摘要:
以水库蓄水后在黄土梁的另一侧诱发的赵家岸滑坡为例,提出了基于水库蓄水水位控制的滑坡风险分析和控制的方法。在建立地下水数值模型和预测地下水流场的基础上,进行滑坡稳定性分析和可靠度分析,确定不同库水位下的滑坡失稳概率,基于滑坡风险管理的理论,评价不同库水位下的人员生命风险和财产风险,统筹考虑容许风险和供水需求,确定了安全合理的水库蓄水水位,并提出搬迁避让、疏水排水和水位控制等综合风险控制措施。
Abstract:
Based on an analysis of the Zhaojiaan landslide caused by water level rise in the reservoir at the other side of a loess ridge,this paper presents a method to analyze and control the landslide risk through controlling water levels of the reservoir.A groundwater numerical model is set up to forecast the groundwater flow pattern.The stability and reliability of the landslide are analyzed to determine the probability of landslide failure at different water levels.According to the theory of landslid...
