摘　　要：近10多年来,我国围填海工程发展迅速,渤海海岸线变化明显,岸线变化会改变潮波传播并影响风暴潮增水。基于FVCOM海洋动力学模型,利用潮汐和风场强迫,建立了渤海风暴潮模型,根据2000年岸线和2010年岸线,分别模拟了包括台风风暴潮和寒潮风暴潮在内的4次典型风暴潮过程,对模拟数据和实测数据进行统计分析,模拟结果与实测数据基本一致。研究了岸线变化前后,渤海风暴潮对近岸増水的影响,并对曹妃甸港、天津港和黄骅港的风暴潮增水灾害进行了风险评估。The recent decade or so has witnessed proliferating reclamation projects around the Bohai Sea, leading to obvious shoreline change which could in turn change the tide transportation and have some effects on the storm surge. Based on the Finite Volume Coastal Ocean Model （FVCOM）, four typical tropical and extratropical storm surges are produced with tidal parameters and wind field compelling using the 2000 and 2010 coastline, respectively. The hydrodynamic model is forced by using wind data obtained from the Weather Research forecasting Model （WRF）. The simulated storm surges agree well with the observed data. The impact of shoreline changes on storm surge in the Bohai Sea are analyzed in a detailed manner. The probabilities of potential storm surge disasters are studied and evaluated on the areas of Caofeidian Port, Tianjin Port and Huanghua Port.
