阶梯溢流坝综述

Overview of staircase spillway dams

对国内外已建成的几十座阶梯式溢流坝所取得的丰富成果作了综述。目前应用的阶梯溢流坝主要是将传统的光滑溢流坝面改成具有阶梯状的溢流面,现有的成果大部分是针对其消能特性,即阶梯使过坝水流的能量损失增大所作的讨论。也从阶梯面的压力分布、掺气特点等方面概述了国内外对阶梯坝水力特性的研究现状。

The paper gives an overview of dozens of staircase spillway dams in the world. The staircase spillway dams derive from the smooth surface spillway dams. Most achievements focused on the characteristic of energy dissipation, that is, the staircase dissipate more water energy when water flows down. Moreover, The paper sums up the present situation of study on pressure distribution and doping gas, etc.
