摘要
针对波浪对深水桥墩的作用,不同波浪参数的形式对深水桥墩波浪力的影响大小和程度各不相同,这就需要对深水桥墩在设计和施工阶段需要采取有效的应对方法。以CFD数值计算的方法为基础,对大直径圆形的深水桥墩在不同波长和波高的三维波浪参数条件下受到的波浪力分别进行了计算,并得到了各自的大小,数值计算结果表明波长和波高的规则的增长,波浪力也基本上呈规则的变化,并且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,到达某一深度减小为零,同时波长和波高的增加都会扩大波浪力在墩柱上的影响范围。
In view of the waves action with deep water piers, according to different wave parameters, the wave force influence is not identical, this problem needs take effective methods to solve in design and construction stage. In this paper, based on the method of CFD numerical simulation, the wave force of deep water piers under the different wave parameters condition is calculated respectively, and the value of the respective wave force is calculated. The numerical calculation results show that the wave force pres- ents basically a rule change with the rules growth of wave length and wave height. Alone the free surface to the bottom of the pier, the wave force is gradually decreasing. Until reached to a certain depth, the wave force decreases to zero. At the same time, the wave force will expand the scope on the pier increasing the wave length and wave height.
