锦屏水电站大沱生活营地后坡稳定性分析
|
摘要
通过室内试验与土体物理力学参数反分析相结合,综合确定锦屏水电站大沱后坡岩土体物理力学参数。在此基础上,利用传递系数法对边坡进行稳定性计算,结果表明:在天然情况下为基本稳定-稳定状态;在暴雨条件下,后坡局部表层失稳,整体稳定。
Through indoor test combined with soil mass physical and mechanical back analysis,physical and mechanical parameters of rock and soil mass of Datuo back slope of Jinping Hydropower Plant are determined.On that basis,slope stability is calculated with transfer coefficient method.It is educed that slope is under basic stable to stable state under natural condition.Under rainstorm condition,back slope local surface losses stability,but the whole is stable.
