【摘要】 小岛综合开发的前提在于土地资源的供给与大陆经济腹地的联系,其中前者往往是制约性的因素。舟山市金塘岛自金塘大桥建成后,区域优势十分明显,金塘岛北部小岛众多,岛群间的连岛造地是解决该区域土地资源紧缺的主要途径。连岛造地工程将改变周围的水动力条件,势必引起海域泥沙输移的变化,重新调整海床高程,使之与水流相适应,采用二维潮流数值模型结合经验公式预测工程实施后潮流场和海床的变化,为工程决策提供技术依据。更多还原

【Abstract】 Comprehensive development of islands lies in land supply and connection with economically developed hinterland,the former one often being a constraint factor.Since the completion of the Jintang Bridge,the Jintang Island in Zhoushan city has embraced prominent regional advantages.Land reclamation by connecting numerous small islands to the north can be a major way to solve land insufficiency of the Island.The land reclamation project will alter the surrounding hydrodynamic condition,resulting in change of sediment transportation in the sea,and readjustment of seabed elevation to suit currents.By adopting a 2D current numerical model in combination with empirical formulas,predictions are made regarding the change of tidal current field and seabed,which can be of technical value to engineering decision-making.更多还原
