一、引言水跃消能不受地质条件限制,运用稳定、安全可靠、消能效果良好,故大多数中小型工程惯于采用,但水跃消能的消力池、池后海漫及消力池两侧边墙工程量均较大,故工程造价较高;戽流消能的消能效果良好、节省投资、方便施工等优越性均较突出,其缺点是戽内消能率较低,戽后余能较大,下游波浪剧烈且延伸较远,岸坡冲刷严重。本文所提出的陡坡戽跃联合消能,则是利用溢洪道陡坡,使消能体 I. INTRODUCTION Hydrostatic energy dissipation is not limited by geological conditions. It is stable, safe and reliable with good energy dissipation effect. Therefore, most small and medium-sized projects are accustomed to adopting. However, The project volume is large on both sides of the pool, so the project cost is higher. The energy dissipating effect of jet stream energy dissipation is good, saving investment and convenient construction are all outstanding. The disadvantage is that the energy dissipation ratio in the jet is low, After more energy, the downstream wave of intense and extended far, serious erosion of the bank slope. The proposed steep slope jump joint energy dissipation, it is the use of steep slopes spillway, so that the energy dissipater
