摘　　要：本文对富尔江尾水渠的原设计方案和两种修改方案进行噪声模拟试验。以流体声学相似原理为依据,利用古典声学理论对背景噪声进行分析与修正,评估降噪的效果,确定跌水坎的修改形式,为工程建设提供参考依据。This paper modeling the original design form and two redesign forms of energy dissipater. Based on the principles of acoustic similarity, Analysing and retouching background noise, acoustic wave reflecting, intervening and splicing with classic sonic theory. Evaluating the effect of reduce noise. Choose the suit form of energy dissipater, offer datas to engineer constructing.

关 键 词：声学相似原理 马赫数 背景噪声
