【摘要】：以龙口湾正在兴建的龙口人工岛群和招远人工岛群为例,利用MIKE21软件建立龙口湾人工岛群附近海域水沙数学模型。在模型经过实测资料验证的基础上,设计了两大人工岛群整体建设和间隔期不同的分期建设方案,模拟不同方案对龙口湾潮流变化和海底冲淤演变的影响。结果表明,间隔期为9 a的分期建设方案中人工岛群水道内流速较大,周围海域泥沙运动相对稳定,确定为优选方案。
[Abstract]:Taking Longkou artificial island group and Zhaoyuan artificial island group which are under construction in Longkou Bay as examples, a mathematical model of water and sediment near Longkou Bay artificial island group is established by using MIKE21 software. On the basis of the verification of the measured data, two artificial island groups are constructed and constructed in different phases, and the effects of different schemes on the tidal current change and submarine scour and deposition evolution in Longkou Bay are simulated. The results show that the velocity of the artificial island group waterways is larger and the sediment movement in the surrounding sea area is relatively stable in the phased construction scheme with an interval of 9 years.
