【 摘 要 】

In order to study the relationship between the water noise of the rubber dam and the different hydraulic conditions including the different discharge and the plunge pool conditions, this paper proposes the detailed analysis supported by the model test. Besides, the tail ridge and the length are also considered, respectively. A number of noise measurement points with 10cm spacing are arranged along the length, width and height of the plunge pool in the downstream of the rubber dam model. The noise of different measuring points in different conditions is measured and analyzed by using the noise spectrum analyzer. The results show that while the flow and the plunge pool length are the same, the water noise decreases with the tail ridge height increasing; while the flow and the height of the plunge pool tail ridge are the same, the water noise decreases with the length of the plunge pool increasing; while the length of the plunge pool and the height of the plunge pool tail ridge are the same, the water noise increases with flow increasing.
