摘要
针对库区滑坡失稳及滑体高速入水引起的涌浪可能对库岸安全及水库运行造成的危害,以金沙江梨园电站库区草可都滑坡为例,应用有限元分析软件计算出该滑坡在库水位升降条件下的稳定性,运用能量法及潘家铮涌浪计算理论对其滑速、初始涌浪及沿程涌浪高度进行了计算。计算结果表明,草可都滑坡整体失稳时引起的涌浪会威胁到对岸各基河电站的安全,但对下游坝址的影响很小;局部失稳时,涌浪对对岸电站厂房及坝址的影响都很小。
Aiming at the hazards of reservoir bank safety and reservoir operation leaded by slide loosing stability and slide bodies entering the water at a high speed,taking the Caokedu landslide in Liyuan reservoir as an example,using finite element analysis software,this paper calculates the stability of the slope with changing water lever,and calculates the sliding speed,the initial surge height,and the along height of the surge by using energy method and Pan Jiazheng surge calculation method.The result shows that the surge appeared by the loosing stability of whole Caokedu landslide will threaten the safety of each power station on the opposite band of the base river,but the impact is little to the downstream dam site.During the partly loosing stability,the influence of surge to each power station plant on the opposite band and the dam site is very little.
