| 摘 要： | 本文采用ECOM-SED模式、算子分裂法和“干、湿”点法建立了胶州湾变边界数值模型。从潮、余流、潮波系统和潮流能几方面预测分析了胶州湾前湾追地对海洋水动力的影响。结果表明，前湾填海对胶州湾的潮波系统影响甚微，振幅和位相的变化都在1％以内。但是在前湾和工程附近海域潮流和余流变化比较大，其他海域的潮流和余流变化不大，潮流流速变化为1％左右，余流流速变化为3．14％～9．16％。填海后，内湾口和外湾口附近潮能通量增加2．6％～5．24％，前湾和工程局部区域潮能通量减小20．21％～87．23％。

| Abstract: | In this paper,the ECOM-SED model,the operator splitting technique and the dry and wet point concept are used to formulate a variable boundary numerical model for the Jiaozhou Bay,and the numerical model is then used to analyze and pridict the effects of reclamation in forebay on marine hydrodynamics from three aspects of tidal and resid- ual currents,tidal wave system and tidal current energy.It is shown from the analysis results that the sea reclamation in forebay has little effect on the tidal wave system in the Jiaozhou Bay,and the variations in tidal wave amplitude and phase will be less than 1%.However,the variations in tidal current and residual current in the forebay and the reclamation project neighboring sea area will be considerable,and the variations in tidal current and residual current in other sea areas will be small with the varitions in tidal current speed and residual current speed being about 10% and 3.14% to 9.16%,respec- tively.After the sea reclamation,the tidal energy flux near the inner and outer bay en- trances will increase by 2.6% to 5.24%,but the tidal energy flux in the forebay and the reelamation project sea area will decrease by 20.21% to 87.23%. |
