针对波浪对深水桥墩的作用,不同截面形式的深水桥墩受到同一种波浪参数的波浪力的影响大小各不相同,这就需要对深水桥墩在设计和施工阶段采取有效的应对方法。该文以CFD数值计算的方法为基础,对圆形和方形截面形式的深水桥墩在相同三维波浪参数作用下分别进行了计算,并得到了各自波浪力的大小,数值计算结果表明:圆形墩柱受到的波浪力要小于边长为圆形直径的方形墩柱的波浪力,并且在墩柱自由水面向墩柱底部垂直深度方向的分布上,波浪力逐步减小,在到达某一深度上波浪力减小为0,并在此深度之下保持不变。
In view of the effect of waves on deepwater piers, the influences of wave forces of the same type of wave parameters on the deep-water piers of different cross-sections are different, which requires an effective response to the design and construction of deep-water piers. Based on the CFD numerical calculation method, the deepwater piers with circular and square cross-section are calculated under the same three-dimensional wave parameters and their respective wave forces are calculated. The numerical results show that the circular piers The wave force exerted by the column is smaller than the wave force of a square pier with a circular diameter on the side, and the wave force decreases gradually along the distribution of the vertical depth of the free column of the pier towards the bottom of the pier. At a certain depth The wave force is reduced to zero and remains constant below this depth.
