摘　　要：通过模型试验,研究了X型宽尾墩作用下短消力池内的动水荷载特性,分析了底部开口高度对溢流坝面以及消力池的影响,并对宽尾墩底部开度进行了优选,结果认为宽尾墩底缘开口1.5 m为最佳方案。试验结果对工程设计具有一定参考价值。Based on the relevant model test, the characteristics of hydrodynamic load under the effect of X-shaped flaring gate pier in short stilling basin is analyzed herein ; in which the analysis on the influence from the height of the bottom opening on the surface of the spillway and the stilling basin is made, and then the bottom opening of the flaring gate pier is also optimized. The result shows that the height of 1.5 m for the bottom opening is the best scheme. The study result has a certain reference value to the engineering design concerned.
