填海造地对胶州湾水动力环境影响的数值研究

Study on impact of Jiaozhou Bay sea-filling on hydrodynamic environment

以胶州湾为例 ,应用分步杂交方法建立了胶州湾变边界潮流数值模型 ,并对其进行了模拟计算 ,重现了该海域的潮流分布规律。另外 ,根据几个填海方案 ,分别进行了预测计算 ,从而得到了各方案分别实施时对潮流、水位、流通量等水动力因素带来的影响。结果表明 ,填海面积越大 ,影响也越大 ,截流填海比顺流填海影响大 ,强流区填海比弱流区填海影响大。

A varied boundary tidal current numerical model of Jiaozhou Bay is established using the split steps finite element method. The current distributing pattern of this area is modeled by calculation. Predictions are made according to several sea filling plans, and the impact of the hydrodynamic factors such as tidal current, water level, etc. are obtained. It shows that the bigger the area filled and the more the impact and that the effect of blocking currents is larger than that of downstreams, and that the effect in the area of high current is stronger than that in the area of low current.
