不同条件下WES堰下泄水流水噪声试验研究

Analysis of the Water Noise Value of the WES Weir Under Different Conditions

通过对不同的消力池尾坎高度、不同的消力池长度、不同流量下WES堰下泄水流水噪声进行测量,研究WES堰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WES堰下泄水流声压大小,随尾坎高度提高,水声压降低;在上游来水流量、消力池尾坎高度相同时,WES堰下泄水流声压随着消力池长度的增长而下降;在相同消力池长度和尾坎高度情况下,WES堰下泄水流声压随流量的增大而总体上升。

In order to study the relationship between the water noise of the WES weir and the flow from the upstream and the plunge pool condition,it measured the water noise of the WES weir under the different plunge pool tail ridge heights,different plunge pool lengths and different discharges. The analysis results show that the height of the plunge pool tail ridge will influence the water noise of the WES weir 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 increases of discharge while the length of the plunge pool and the height of the plunge pool tail ridge are the same.
