| 摘 要： | 以模型试验的形式,研究溢流堰下泄水流噪声问题。试验选定宽顶堰和WES堰进行研究,设定3个流量,测量并记录下泄水流噪声频谱值,对其进行分析。结果表明:相同堰型相同测点的噪声随流量增大而加大,相同堰型相同流量的噪声最大值出现在溢流堰与尾坎之间;WES堰的最大噪声值比宽顶堰的最大噪声值大1dB,而其最小值比宽顶堰的最小噪声值小8dB,说明噪声频谱值的大小与堰型、流量等因素有关。

| Abstract: | WES Weir and Broad Crested Weir were selected with 3 flows,to measure and record the noise spectrum value of discharge flow.The results showed that in the condition of the same type of the weir and the same noise measuring point,the value increased with the flow rate.In the condition of the same type and the same flow weir noise maximum was between the bucket overflow weir and tail.The maximum noise value of WES Weir was 1dB bigger than that of Broad Crested Weir,while the minimum noise value was 8dB smalle... |
