摘　　要：本文通过对瀑布沟、水口、龙滩、拉西瓦等大型水电站闸门水封的模型实验分析与水封的非线性仿真计算结果进行分析、研究与对比表明:不但能优选水封断面结构型式,而且还得到了水封的水密性规律及封水判据;并通过实例加以判断和验证。这样就可以用水封的非线性仿真计算结果来判断所设计的水封能否可靠封水,从而减少了耗时费钱的模型实验验证工作。This paper presents the results of nonlinear simulation and model test of the gate water-seal adopted in the large-scale hydropower stations of Pubugou,Shuikou,Longtan and Laxiwa.Detailed analysis and comparison of these results demonstrate the optimization of the water-seal cross section and the variation of hermetic capability.A water-stop criterion is proposed and verified by scale model test.It is shown that the effectiveness of a water-seal can be judged by using the simulation results and the costly and time consuming model test should be avoided.
