| 摘 要： | 海湾内的围垦工程对潮流及冲淤都将产生影响.以三门湾蛇蟠和下洋涂围垦工程为例,设计了3组试验对比的数值模拟计算方案,对比计算结果表明,预测三门湾内2个围垦工程对水动力环境产生的影响,当讨论单一围垦工程时,应把工程前的海湾状态设置为湾内没有任何其它工程,这样才能得出单个围垦工程对湾内环境的真实影响;当讨论2个围垦工程对水动力环境产生影响时,应进行2个围垦工程整体数学模拟计算,考虑2个围垦工程的叠加累积影响,并与海湾原始状态(即假定海湾在围垦前湾内没有任何其它围垦工程)进行比较,才能得出较为科学的预测结果.

| Abstract: | Gulf reclamation project has an impact on the trends and siltation.Taking Shepan and Xiayangtu reclamation in Sanmenwan Bay as the example,we designed three contrastable numerical simulations.As calculations indicate the forecast of two bays reclamation works on the hydrodynamic environment,when a single reclamation project is discussed,former state should be set up with no other projects,so that we can draw the real impact of the hydrodynamic environment on individual reclamation.When discussing two reclamation projects, mathematical modeling of the whole should be carried out on two reclamation projects.Taking into combined cumulative effects on two reclamation projects,and comparing with initial state(no other reclamation in the bay),it is possible to draw more scientific forecasting results. |
