摘要
巴溪生态坝水流噪声超标,造成周边居民生活极大不便。针对此问题,经坝体水力过流特征分析,水流异响很可能是由于坝体剖面设计不当引起的。本文提出了3种剖面优化设计方案,分别是坝面加糙、坝面加高和坝顶降高。通过水工模型试验方法,最终得出降低坝体高度是实现工程减噪最有效的方法,试验结果可供类似工程参考。
The noise of the water flow in Baxi Ecological Dam exceeds the standard,thereby causing great inconvenience to the surrounding residents.The abnormal water flow noise is probably caused by the improper design of the dam profile in view of the problem through the analysis on the characteristics of hydraulic flow of the dam body.Three optimal profile design schemes are proposed in the paper,namely roughness of dam surface,height increase of dam surface and height reduction of dam top.It is finally concluded that the height reduction of the dam is the most effective way to reduce the noise of the project,and the test results can be used as reference for similar projects through the hydraulic model test method.
