潍坊港新规划港区波浪与泊稳的数值模拟

Numerical simulation of wave and mooring stability in new planning port area of Weifang Port

针对潍坊港新规划港区的波浪入射及泊稳问题,采用梯级嵌套波浪数值模拟方法,对2 a一遇波浪条件下的潍坊港中、西港区内波浪折绕射进行研究。结果表明,在正对口门入射的ENE及NE向波浪作用下,小口大腹的港区形态有助于削减口门入射至港区腹内的波浪强度,港内码头区大部分水域比波高在0.3以下;中港区靠近口门两个特征点的波高H4%相对较大,均为0.86 m,至中港区顶部的比波高迅速削减至0.2以下;西港区波浪以风浪为主,各特征点的波高H4%介于0.46~0.66 m,至西港区顶部的比波高迅速削减至0.1以下;各泊位均能满足泊稳条件。

Aiming at the problems of the wave incoming and mooring stability in the new planning port area of Weifang Port,we apply the numerical simulation method of the cascade nested wave,study the wave refraction and diffraction in Weifang Port’s central and western port areas under the recurrence period of two years.The results show that under the functions of wave in ENE and NE direction,the small gate and big abdomen port area can significantly reduce incoming wave intensity from the entrance to the belly,and the specific wave height of most waters in wharf area is under 0.3.Meanwhile,the wave heights of H4%of two feature points at the entrance of middle port area are relatively large to 0.86 m,and the specific wave height at the top of central port area is rapidly reduced to below 0.2.Waves in the western port area are mainly wind waves.The wave heights of H4%of west port area at feature points range are from 0.46 m to 0.66 m,and the specific wave height at the top of western port area is rapidly reduced to below 0.1.Each berth can satisfy the stable condition.
