摘要
取水明渠柔性拦截网受波浪作用上下运动,有限振幅波理论中的水质点位置难以确定,导致波浪力计算存在困难。基于水池试验方法对波浪力形成的速度理论计算方法进行修正。结果表明,波浪力水质点位置与波高以及波周期相关,修正公式计算值与试验结果误差小于20%,符合性较好。研究成果对于拦截网的承载力设计和运行监测具有一定的指导作用。
Interception nets in intake channel are currently the key means to respond to the intake blockage causing by marine organisms.However,in actual operation,there have been multiple incidents of failure caused by the blockage of interception net.In order to study the hydrodynamic characteristics of waves in planar interception net,theoretical calculation methods were analyzed.Based on physical model testing methods,the theoretical calculation method for the formation of wave forces was explored.The position of water quality points in the water depth direction was discussed.The research results show that the error between the calculated values and the model test results is less than 20%,indicating good consistency.The results have a certain guiding role in the design of the capacity of the interception net.
