【摘要】 拟建的某水电站位于雅砻江上游大河湾的下游段,是雅砻江流域规划拟建的最大库容水电站。该滑坡位于拟建I勘探线下游约300m的左岸陡倾顺向坡中。通过采用3种极限平衡法对它进行了稳定性计算,结果表明:在天然情况下,滑坡体处于平衡状态;在特大降雨情况下,滑坡发生整体失稳的可能性不大,但有可能发生局部的失稳。为了使坡体处于稳定状态,除了常规的工程治理措施外,有必要对它采取生物护坡措施,以减少水对滑坡体不利影响。更多还原

【Abstract】 A hydroelectric station lies in the lower reaches of Dahewan,upstream of the Yalong River.This hydroelectric station is connected to the biggest capacity reservoir in the Yalong River.One of the slopes of the reservoir is very steep.If this slope fails it will harm thousands of people who live up slope.Calculations of the slopes stability,using three methods,indicates that the slope is safe under natural conditions,although under unusual weather conditions it could partially fail.In order to ensure the stability of the slope bio-controlling measures were implemented to reduce any adverse effects on the slope stability.更多还原
