摘　　要：本文利适合涌浪计算的二维非恒定流数学模型.对电站机组紧急关闭产主的涌浪运动进行的数值模拟.从数值成果看出.电站紧急关闭产生的涌浪的水面升降激烈.波陡大.具有一定的破坏性.在文章的未尾.给出了这种涌浪的计算公式.供有关部门参考.In this paper,the movement of surge produced by rapid change in powerhouse is imitated by 2 -D mathe matcal model uhch can be used in surge calculation. According to mathmatical model's results,we know immediately raise and down of water level in channel can cause damage. In the end of paper, formula about the surge is presented.
