Box-type horizontal plate of twin-plate breakwater structure

双层水平板式防波堤是一种新型的水工结构物,采用上下两层水平板达到消浪、透水的目的。本文研究的水平板采用钢制箱型板结构。根据物理模型试验测定的波浪荷载,应用ANSYS有限元软件,分别探讨不同支承形式、钢板厚度、H型钢加劲肋个数和型号等因素对水平板应力和变形的影响,并与传统计算方法相比较,为双层水平板式防波堤的结构设计及工程应用提供参考。

The twin-plate breakwater is a new type of harbor engineering structure using twin horizontal plates to attenuate waves and permeate seawater.The horizontal plate expounded in this paper uses steel box-type plate structure.According to the physical model tests,this paper investigates the influence of different supporting forms,different thicknesses of steel plates,different numbers and model numbers of H-beam stiffeners on the stress and deformation of the horizontal plate by the finite element software ANSYS.Comparing the numerical simulation results with those by the traditional calculation method,it provides a reference for the structure design and engineering applications of twin-plate breakwater.
