摘要
双挡板透空防波堤消浪效果好,具有过水性、环境友好等特点,可满足海洋环境保护对水工建筑物的要求。针对目前该类结构水动力特性研究不足的问题,对波浪作用下双挡板透空防波堤波浪荷载进行研究。基于Fluent模型建立数值水槽,模拟波浪与双挡板防波堤作用,分析板间不同水面条件下,相对水深、挡板入水深度、堤宽等因素对波浪荷载的影响。结果表明,当双板间为非自由水面时,结构荷载受相对水深和堤宽影响较小,随入水深度增大而增大;当双板间为自由波面时,板间水体运动显著影响结构的受力,结构最大荷载会明显增大,结构荷载与各影响因素间关系也产生变化。双板间自由波面条件是防波堤常见的工作状态,在结构设计时应充分重视。
The open type breakwater with double baffles has good wave attenuation effect,and has the characteristics of water permeability and environmental protection,which can meet the requirements of the functions of structures due to the marine environmental protection.A study on wave loads acting on a opentype breakwater with double baffles under wave action is conducted to address the current shortcomings in hydrodynamic characteristic research of such structures.A numerical flume is built on the basis of the Fluent model,and the interaction between waves and the breakwater with double baffles is simulated.Then the influence of relative water depth,depth of baffle into water,width on wave load under different wave surface condition between two baffles is analyzed under different water surface conditions between baffles.The results show that when there is no free water surface between the two baffles,the structural load is less affected by the relative water depth and width of breakwater,and increases with the increase of depth into water.For the free wave surface condition,the water movement between the baffles significantly affects the wave load of the structure,the maximum load of the structure will increase significantly,and the relationship between the structural load and the influencing factors will also change.The condition of the free water surface between the two baffles is a common operational state for breakwaters,and it should be given full consideration during the structural design process.
