摘要
通过在不同的消力池尾坎高度、不同的消力池长度、不同的流量下对橡胶坝下泄水流水噪声进行测量,研究橡胶坝下泄水流与上游来水流量及下游消力池状况的关系。结果表明:在流量、消力池长度均相同的条件下,尾坎高度的改变会影响橡胶坝下泄水流噪声值大小,随尾坎高度提高,水噪声值降低;在相同的上游来水流量、消力池尾坎高度相同时,橡胶坝下泄水流噪声值是随着消力池长度的增长而下降;在相同的消力池长度和尾坎高度情况下,橡胶坝下泄水流噪声值是随着流量的增大而总体上升。
In order to study the relationship between the water noise of the rubber dam and the flow from the upstream,the plunge pool condition,it measured the water noise of the rubber dam under different plunge pool tail ridge height,different plunge pool length and different flow.The analysis results showed that the height of the plunge pool tail ridge will influence the water noise of the rubber dam while the flow and the length of the plunge pool are the same,the water noise reduces with the height of the plunge pool tail ridge increasing;the water noise reduces with the length of the plunge pool increasing while the flow from the upstream and the height of the plunge pool tail ridge are the same;the water noise increases with the flow increases while the length of the plunge pool and the height of the plunge pool tail ridge are the same.
