摘要
直墙建筑物在近海、近岸工程中广泛应用,研究复杂海浪传播后在直墙前的波高分布规律有重要的工程意义,多向不规则波对直墙作用后的波高分布更符合实际工程需求。采用数值模拟的方法对不同入射波向的多向不规则波在直墙前的传播过程进行模拟,通过对得到的实时波面数据计算、统计,探讨多向不规则波在直墙前反射、叠加后的平面波高空间分布,得到了多向不规则波波高腹点、节点间距与波长的关系。可为近岸、近海工程建设提供设计依据。
Straight wall buildings are widely used in offshore and coastal engineering.It has important engineering significance to study the wave height distribution law in front of a straight wall after the complex propagation of ocean waves.The distribution of wave height after the multi-directional irregular wave acts on the straight wall is obviously more in line with the actual engineering needs.We used numerical simulation to simulate the propagation process of multi-directional irregular waves with different incident wave directions in front of a straight wall.Through the calculation and statistics of the calculated real-time wave surface data,the plane spatial distribution of wave height after the reflection and superposition of multi-directional irregular waves reflected in front of a straight wall was discussed,and the relationship between multi-directional irregular antinodes,node spacing and wavelength was obtained,which provides design basis for nearshore and offshore engineering construction.
