摘要
依托乌江银盘水电站,对底流消能消力池底板及导墙脉动压力特性进行了较系统的水力学模型试验研究。通过大量点、面水流脉动荷载测试数据的综合分析,获得了消力池底板及导墙动水压力的分布规律。该研究丰富和发展了底流式消力池及导墙的脉动压力特性研究,可为对该类消能形式水流动力特性的深入研究提供科学参考。
Based on Yinpan hydropower station on the Wujiang River, a systematic hydraulic model test has been made on the characteristics of fluctuating pressure on the bottom floor of stilling basin and guide wall. Through comprehensive analysis of fluctuating load testing data of many points and surfaces, the distribution law of hydrodynamic pressure on the stilling basin bottom floor and guide wall is obtained. The paper presents and develops the research on the fluctuating pressure characteristics of the stilling basin for energy dissipation by hydraulic jump and the guide wall, so reference can be made for further research on hydrodynamic characteristics of such type of energy dissipation.
