一种改善消力池底板压强分布的新型宽尾墩——XT型宽尾墩

A New Type of Flaring Gate Piers for Improving the Pressure Distribution on the Stilling Basin XT Flaring Gate Piers

宽尾墩与消力池组成的联合消能形式具有消能率高的特点，但也存在着消力池内的压强分布不均匀，最大冲击压强及动水压强集中度过大的问题。本文结合功果桥水电站整体水工模型试验，提出了一种新型的XT型宽尾墩，对于改善消力池底板上的压强分布，增强底板的稳定具有重要意义。

Though the energy dissipation efficiency associated of flaring gate piers with stilling basin is higher, there still are some drawbacks, such as non-uniform pressure distribution and over concentration of hydrodynamic pressure in stilling basin. A new XT type of flaring gate piers is introduced in the paper, it was shown by hydraulic model study that it had an outstanding effect of improving pressure intensity distribution in stilling basin.
