针对规则波浪对不同截面形式的深水桥墩波浪力的影响大小各不相同的问题,利用CFD数值计算的方法,对不同截面形式的深水桥墩在不同波长和波高的波浪参数条件下受到的波浪力分别进行了计算。结果表明:在其他条件相同的情况下,截面尺寸越大,产生的波浪力越大,并且波长和波高的规则增长,波浪力也基本呈规则的增加;波浪力在墩柱自由水面下垂直深度方向的分布上是逐步减小的,在某一深度减小为零,波长和波高的增加都会扩大波浪力在墩柱上的影响范围;把计算得到的波浪力作用于不同尺寸的墩柱上,尺寸越大在墩顶的最大位移越小,在墩底产生的最大应力越大,固有频率越高。
Aiming at the problem that the influence of the regular wave on the wave force of the deepwater pier with different cross sections is different, the wave forces on the deepwater piers of different cross sections under the wave parameters of different wavelengths and wave heights are respectively calculated by the CFD numerical method Calculated. The results show that under the same conditions, the larger the section size is, the larger the wave force is generated and the regular increase of the wavelength and wave height is. The wave force also increases in a regular way. The wave force is in the direction perpendicular to the free surface of the pier The distribution is gradually reduced, at a certain depth reduced to zero, the increase of wavelength and wave height will expand the influence range of wave force on the pier; the calculated wave force acting on different sizes of piers, The larger the size is, the smaller the maximum displacement of the top of the pier is, the larger the maximum stress generated at the bottom of the pier is and the higher the natural frequency is.
