摘 要:随着城市河流治理,河道上泄水建筑物产生的水流噪声开始严重影响附近居民的生活,而噪声产生的机理和防治研究相对较少,以浑河为对象,对其上橡胶坝、翻板闸及滚水坝3种类型泄水建筑物下泄水流噪声进行监测,测量不同类型泄水建筑物下泄水流在相同的条件下噪声变化。结果表明:在相同流量条件下,3种泄水建筑物噪声,橡胶坝最大,其次是渠首滚水坝,最后是翻板闸。泄水建筑物噪声都属于中低频噪声,且距建筑物距离越大噪声值越小。With the city river harnessing, the flow noise produced by river discharge structure seriously affected the life of residents nearby, yet the study on mechanism of producing and control of the noise were relatively less. Taking HunHe River as study object, monitoring of the sluice flow noise produced by three types of river discharge structure: rubber dam, flat flap gate and overflow dam were carried out and the noise changing of different types were measured under the same sluice flow condition. The results showed that the largest noise is rubber dam, the second is overflow dam, the last is flat flap gate under the same flow condition. The sluice flow noise belongs to medium and low frequency noise, and the longer distance to the discharge structure was, the smaller noise val ue would get.
