椭圆余弦内波作用下沿海电厂卸煤码头墩柱受力分析

将沿海电厂卸煤码头简化为只有2排4个墩柱,模拟了沿海椭圆余弦内波的生成,并且得到了不同周期和波高下椭圆余弦内波的波浪形态.在特定的周期和波高条件下进行了三维椭圆余弦内波作用于码头墩柱的数值模拟,分析了墩柱上受到的惯性力和粘性力的变化趋势,得出墩柱上受到的波浪力呈现周期性变化并且第2排墩柱受力小于第1排的受力.

Mechanical Behavior Analysis of Coal Dock Pillars With Internal Cnoidal Wave Action

Coastal power plant coal dock is simplified to have only four pillars in two rows in this paper.The generation of coastal internal cnoidal wave is simulated and the wave shapes with different amplitudes and different periods are obtained.The wave with specific period and amplitude is chosen for numerical simulation of the forces acting on pillars of coastal power plant coal dock with internal cnoidal wave action in three-dimension.The variation tendency of the inertia force and the viscous force acting on the pillars are analyzed.It is concluded that the forces acting on the pillars vary in period and the force acting on the second row pillars is smaller than that on the first row ones.
