摘　　要： 溢流重力坝是最广泛采用的坝型之一。为了减少坝体工程量，加大流量系数，本文就ＷＥＳ剖面曲线形式，挑流消能在不同挑角下坝高Ｐ１／Ｈ与挑距Ｌ／Ｈ的关系，以及面流和底流消能的堰面尺寸进行了讨论。介绍了用迭代法求解收缩断面水深，以便确定底流消能的有关尺寸。此外，还介绍了遇有完整基岩和软弱结构面时齿墙尺寸的确定。Spillway gravity dam is one of the most widely used dam types. In cider to reduce the volume of dam concrete, WES dam curve is provided. To choose an appropriste flow bucket angle andthe trajectory distance, the relationship of dam height P1/H and the trajectory distance L/H with different bucket angle are demonstrated. In the paper, the iteration method to solve the problem of contracted water depth is also recommended. Besides,. considering the geolosical condition of the bedrock,the size of cut-off wall is determined according to whether the bed rock is solid or weak structural surface existed.
