波流联合作用下平面拦污网衣系泊动力响应特性研究

Study on mooring dynamic response of planar intercepting net under the action of waves and currents

近年来,由于赤潮、浒苔等海洋生物灾害频发,加之水母、鱼虾等海洋生物突然性的数量爆发,已成为影响滨海电厂取水系统安全运行的重大隐患。拦污网衣对于电厂取水系统的安全运行有着重要作用。文章通过物理模型试验手段,分析了一种典型柔性拦污网衣——平面网在纯流作用下、波流联合作用下网衣与桩台间系泊力的变化规律与分布情况,并通过量纲分析法得到了网衣系泊点拉力计算经验公式,为拦污网的系缆绳索受力计算提供了依据。

In recent years,due to the frequent occurrence of marine biological disasters such as red tide and enteromorpha,coupled with sudden outbreaks of jellyfish,fish and shrimps and other marine organisms in numbers,the safety of coastal power plant water intake systems has been severely tested.The intercepting net plays an important role in the safe operation of power plant water intake systems.A series of physical model tests has been carried out to investigate the mooring behavior of a typical flexible planar intercepting net between its adjacent pile platform under the combined action of current and waves,and an empirical formula for calculating the mooring force at the mooring point of the net is then derived.
