青岛浮山湾数值化海区建立的研究——浮山湾潮流模型的数值计算

Study on Establishment of Numerical Sea Area in Qingdao Fushan Bay——Establishment of Tidal Current Model for the Fushan Bay

应用二维潮流数学模型(在近岸海域采用不规则三角形网格有限差分方法)对青岛浮山湾的潮流场进行了数值模拟计算,并预测了工程建成后海区流场的变化。数值模拟结果表明,帆船比赛基地港池及附近水域计算区域内验证点的模拟流速与原型观测值一致,较好地再现了浮山湾的流场变化情况,为2008年北京奥运青岛帆船赛场的规划和建设提供了科学依据。

In this paper, the finite difference technique with irregular triangular grids is used to make a numerical computation based on a two-dimentional tidal current model for Qingdao Fushan Bay, and the numerical simulation of tidal current field in the Fushan Bay is made to predict the variations in the current field after the engineering is completed. It is shown from the simulated results that the simulated variational processes of current velocities at the verification points are consistent with the observed data, and the model has well simulated the variations in current field in the Fushan Bay sea area, which provides scientific basis for planning the Olympic sailing regatta ground in Qingdao.
