摘要
针对滑坡失稳和滑体高速入水激起涌浪可能给水库运行造成危害,综合应用极限平衡法和FLAC3D有限差分法,求解最危险滑动面,确定滑体位置和范围,并联立潘家铮法计算滑体滑动速度、涌浪高度及其传播对坝区的影响,可以较好的预判滑坡危害程度和规避地质灾害风险,保障水库的安全运行,具有较高的工程应用价值和意义。
Based on the hazards of reservoir operation caused by landslide instability and surge, aroused by slide bodies entering the water at a high speed, an integrated research combined with the limit equilibrium method and FLAC3D has been taken to solve the most dangerous sliding surface, make sure that its location and extent, and the Pan Jiazheng Method is applied to simultaneously cal- culate the sliding speed of slide bodies, the surge height and its influence on dams when spread, which can better predict the damage degree of landslide and avoid geological disaster risks to ensure the safe operation of the reservoir, have a higher engineering applica- tion value and significance.
