水布垭水利枢纽泄洪消能方案比较研究

 通过1∶165概化模型试验，探讨了适合该工程可能的消能型式。在1∶100整体模型和1∶88断面模型上分别研究了一级挑流消能方案和底流接挑流的二级消能方案的水力学特性，并结合溢洪道布置、工程量等对一、二级消能方案进行了综合比较，推荐一级消能方案为初设阶段的基本方案。

Comparative Study on Schemes of Flood Discharge and Energy Dissipati on for Shuibuya Project

Abstract According to the features with high head,large unit discharge and worse geological condition downstream spillway of the shuibuya project ,a 1∶165 scale generalized model is used to study different dissipaters so as to select a fit one for the project.Then a 1∶100 scale comprehensive model and a 1∶80 scale sectional models are used to study hydraulic properties of the flip bucket dissipater and the combired dissipater with a stilling basin and a flip bucket respectively,Finally,the singal staged bucket dissipater is proposed as primary scheme of dissipater fo design.
