spillway crest

A Calculating Formula for Spillway Capacity of Drowned Wide Crest Weirs

对淹没宽顶堰泄流能力计算公式的探讨

Optimization studies of spillway crest shapes for high overflow dam with sloping upstream faces

上游面倾斜的高溢流坝堰顶形状优化研究

Joint use of the FEM and transition cubic for analysis of flow over a spillway crest

溢流坝水流的有限元&过渡线联合解法

On this basis, the curve shapes and the formulas of upstream crest and downstream crest and those under the breast wall of the spillway dam are presented.

并以此为依据，提出有胸墙的溢流坝的堰顶上、下游及胸璃底缘的曲线型式和相应的计算公式。

The pier arrangement on spillway crest with sloping upstream face is studied by 310 sets of experiments in the paper.

本文通过310组试验，研究了上游面倾斜的溢流坝的闸墩布置。

The reason for the depths at the water drop and overflow spillway crest are smaller than the critical depth computed with the current formula is explained.

同时还对流线的凹向、流线曲率半径及水面坡度对临界水深的影响进行了分析，论证了趺水处和曲线型实用堰堰顶的水深均小于按现有公式计算的临界水深的原因。

In this paper a new method is presented for the determination of the discharge coefficient and the profile of the free surface of a potential flow over a spillway crest.

本文介绍一种确定过坝势流的流量系数和自由表面的新方法。
