摘　　要：针对古水电站坝址的安全性,预测梅里石1号滑坡在极端工况下失稳引发的涌浪灾害,为此采用能量法和谢德格尔法计算滑坡体最大滑速,选取水科院经验公式法和潘家铮法并根据计算得出的最大滑速进行涌浪爬高计算,根据两种涌浪计算方法的适用性及计算结果,结合滑坡区的工程地质条件进行对比分析,结果表明:滑坡在极端工况下发生滑动引发的涌浪灾害,不会对大坝安全产生威胁。For the safety of dam site of Gushui Hydropower Station, it was predicted that surge disaster may arise out of instability of Meilishi Landslide 1 under extreme conditions. For this purpose, energy method and Scheidegger method were adopted for calculating the maximum sliding speed of the landslide, and then together with LWHR experience formula method and Pan Jiazheng＇s Method for calculating the climb height of surge. According to the applicability of these two calculation methods and the calculation results, with comparative analysis of engineering geological conditions in the range of landslide, it was showed that surge disaster arising out of landslide sliding under extreme conditions will not endanger to dam safety.
