青岛海湾大桥对胶州湾潮汐、潮流及余流的影响预测——Ⅲ.预测方法及预测结果

PREDICTION OF IMPACT OF QINGDAO BAY BRIDGE ON TIDE, TIDAL CURRENT AND RESIDUAL CURRENT IN JIAOZHOU BAY——Ⅲ. FORECAST METHOD AND FORECAST RESULTS

在潮流数值模型中,采取了如下办法表示桥墩:桥墩造成的截水面积通过减小水深来实现,桥墩的阻尼通过增加底摩擦实现。根据以上水深处理和水力学实验给出的阻尼系数,在胶州湾及邻近海域计算潮流场基础上,预测了青岛海湾大桥对胶州湾潮汐、潮流及余流的影响。

In the numerical model of tidal current, the piers of the bridge are represented by using the following method: the flow-blocking area of the piers is represented by the reduction of water depth and the resistance of the piers is represented by the increase of the bottom resistance. Based on the above-mentioned treatment of water deppth and the resistance coefficients given by the hydraulic expericment, from the calculated tidal current in Jaiozhou Bay and its adjacent sea, this paper predicts the effects of the Bay-Bridge on the tide, tidal cur rent and resitual current in Jiaozhou Bay.
