| 摘 要： | 在模型试验的基础上,从水力学角度对高拱坝平底水垫塘及反拱水垫塘的水动力特性进行了分析评价。结果表明,无论是水体特性还是水动力特性,平底水垫塘都优于反拱水垫塘;在消能效果方面,平底水垫塘消能率与反拱水垫塘基本一致,二者的消能率均接近95%。

| Abstract: | Based on the hydraulic model test results ,some hydrodynamic characteristics of plane bottom board plunge pool and reversed arch bottom board plunge pool,from hydraulics angle,were analyzed and discussed in this paper. The results show that, be it water volume property or hydrodynamic characteristics ,the shape of plane bottom board plunge pool is better than that of reversed arch bottom board plunge pool. In aspect of energy dissipation effect ,both values of energy dissipation rate of two kinds of shapes of plunge pool are large,both approximately 95%. |

| Keywords: | high arch dam plunge pool impinging pressure hydrodynamic characteristic energy dissipation effect |
