物理模型试验中涌潮的产生和测控

Occurance and Control of Tidal Bore in Physical Modelling Study

在物理模型试验中复演天然涌潮,对其产生机理、变化过程、流域影响、产生的危害、治理方法、能量利用等方面进行研究,意义非常重大。物理模型中可采用多种装置产生涌潮,试验采用变频器控制水泵,在试验河段的上下游均设置闸板的玻璃水槽,研究涌潮产生的流程、控制和测量方法。

The process of the natural tidal bore has been simulated and analyzed in the physical modeling, including the occurring mechanism, variation, impacts on the basin, potential risks, regulation and the energy utilization. This study is very important. In the physical model, the tidal bore can be induced by different devices and the frequency convertor has been used to control the water pumps and the glass flume with the flashboard has been set in the upstream and downstream river in the trial for the study on the occurrence process, control and measurement of the tidal bore.
