中小型闸坝工程在水利工程中占绝大多数，解决好消能防冲问题非常重要。对低弗氏数水跃特点及消力池设计和运行中的问题作了探讨，对跃后保护段问题、多孔闸的开启程序与运行调度及下游水位影响等问题进行了总结讨论。对消力池新型消能工如T型墩消力池及宽尾墩加消力池联合消能方式作了回顾介绍。
Small and medium-sized sluice projects account for the vast majority of water conservancy projects, to solve the problem of energy dissipation and erosion prevention is very important. The characteristics of low Freunds hydrofoil and the design and operation of the stilling pool were discussed. The problems of post-leapfrog section, opening procedure and operation of porous gate, and influence of downstream water level were discussed. The paper reviews the new energy dissipaters such as T-shaped piers and the combination of flaring pier and desalination cells.
