摘　　要：以三峡库区大石板滑坡为例,运用经验公式法和条块运动学分析法两种涌浪计算方法,预测滑坡不同工况下的滑动速度、初始涌浪最大浪高及滑坡入江体积,结果表明该滑坡最大入江体积为420.44万m3,最大初始浪高达21.42 m,涌浪灾害严重,计算结果为其防灾减灾工作提供了科学依据。With the example of Dashiban Landslide in Three Gorges reservoir, this paper presents the empirical formula and slice analysis technique of kinemati, the two methods of surge calculation, that are used to preview the sliding speed, maximal initial surge height and capacity entering the river in different work conditions. The calculation result indicates that the maximal capacity entering the river is 4204400 m^3 , and the maximal initial surge height reaches 21.42 m, both of which will lead to severe hazard. The calculation result can provide reference for preventing and decreasing the landslide hazard.
