一、引言在溢流坝的消能设施中,以挑流鼻坎和底流水跃消力池应用最广,其水力设计理论也较成熟.但在泄水落差较小、单宽流量和下游水深相当大的情况下,这两种消能工在技术经济方面往往趋于不利,而出现较晚(30年代)的消力戽则有可能适用,并有一些基于模型试验的曲线图表可供设计定型参考。我国最早在石泉水电站采用了消力戽,并取得了一批试验 I. INTRODUCTION In the energy dissipation facilities of spillway dam, the hydraulic design theory is more mature with the most widely used hydraulic hopping tank with bottom flow and bottom flow. However, In the case of considerable water depths, both of these energy dissipators tended to be technically and economically unfavorable, while those that appeared later (in the 1930s) were likely to be applicable and some based on model tests were available Design stereotypes reference. China’s earliest Shiquan hydropower station using the consumer Li, and made a number of tests
