| 中文摘要: |
| 在1:35的白山水电站水垫塘消能布置的整体模型上, 利用测力传感器详细地量测了不同泄流工况下, 水垫塘底部不同位置处底板块上的脉动上举力, 获得了脉动上举力的统计资料, 分析了水垫塘底部不同区底板块的受力特征. 模型计算结果与基于瞬变流理论建立的预报公式计算结果十分吻合. 为水垫塘底板块的设计与防护提供了科学依据. |
| 英文摘要: |
| The fluctuating uplift acting on the floor plate of the plunge pool in Baishan Hydropower Project is experimentally studied in 1:35 hydraulic model. The uplift is measured using force transducers installed beneath the plates. The statistical characteristics of the uplift at various position of the pool are analyzed. The experimental result is in good agreement with the calculated results of the formulas based on the theory of transient flow. |
