龙口港扩建工程航道规划潮流分析

文中建立了龙口湾正交坐标系下变网格二维潮流数学模型,利用数值模拟成果分析了龙口湾潮流分布与变化规律。根据潮流分布特点,提出利用屺坶岛对波浪的掩护作用在岛头西部深槽布置新航道走向时,潮流方向与航道交角以及航道横向流速小,有利于航道稳定和船舶航行安全。研究了港口平面规划方案与航道扩建方案共同作用下的港区和航道的潮流变化特征,研究表明:在屺坶岛掩护区内侧沿等深线向布置码头前缘线和航道,通过适当规划可使码头泊位区和航道区水流平顺,潮流流向基本平行于航道走向和码头前沿线。

Tidal flow analysis for channel arrangement of extension for Longkou Port

The 2-D tidal mathematical model of Longkou bay is established in orthogonal coordinate system.The tidal flow characteristic and distributing rule of Longkou bay were analyzed based on the result of simulation.New channel layout that is placed to deep water range of southwest of Qimu island head is proposed,in this place,angle is smaller between flow direction and channel direction,channel is more stabilization and ship movement is more safe.Tidal flow characteristics that were affected on double reaction of port plane layout plan and channel extension plan were researched.The result indicates,with dock and channel planed at the deep water area where is sheltered from Qimu island,the flow field is smooth at the range of dock and channel,tidal flow direction is parallel with channel direction and front edge of the dock.
