WFH双级跌水体型设计

Design of double-stage water drop works for WFH Project

介绍了WFH工程的基本情况。WFH工程渠线地势落差大,流量较大,跌水较多,布置型式分为单级跌水和双级跌水,双级跌水消能池的消能情况较为复杂,在该工程中选择合理的跌水体型是非常重要的。同时跌水的安全运行也是该工程能够安全运行的必要条件。论述了双级跌水水工模型试验的主要内容和测试方法及试验结果,并介绍了双级跌水初始设计和修改方案的主要参数。

An introduction was made on the general information of WFH Project.The channel of WFH Project has large terrain drop,high flow and many water drop arrangements including single-stage drop and double-stage drop.The energy dissipation situation of double-stage drop dissipation pool is relatively complex,so it is very important to select a proper type of water drop for this project.Meanwhile,the safe operation of water drop works is also neces⁃sary for the safety of the project.The author demonstrated main contents,testing methods and results of the hydrau⁃lic model test of double-stage water drop works,and presented main parameters of the initial design scheme and the modified scheme.
