摘　　要：滨海火/核电厂以海水作为冷却水源,取水口所处水域水动力条件十分复杂,其中波浪是取水口结构受到的主要动力荷载。文章以浙能镇海电厂燃煤机组搬迁改造项目循环取水口为例,采用物理模型试验方法研究了波浪作用下蘑菇头式取水口的结构受力情况。试验结果表明,在波浪作用下,取水头受到的总力基本不受相邻取水头的影响,垂向和水平向总力随水位变化,其最大总力发生在不同水位。Thermal or nuclear power plant in coastal area takes sea water as cooling water source, and the hydrodynamicconditions of water intake are very complex, in which wave is the main dynamic load of water intake structure. By taking thecirculating water intake system of Zheneng Zhenhai coal power station relocation project as an example, we investigated waveloads on mushroom shape intake structure using physical model studies. It is found that the total wave force on intake structureis not affected by neighbours. Vertical and horizontal forces vary with water level, the maximum total force occurs at differentwater level.
