| 摘 要： | 自2000年以来围绕渤海湾的围海工程剧增，致使工程区附近潮流场发生变化，进而影响排海高温浓盐水的时空分布特征。本文通过建立2000年和2015年两种不同岸线、地形条件下的三维数学模型对渤海湾沿岸3个电厂高温浓盐水表层排海问题进行模拟，研究结果表明，渤海湾的潮流场和高温浓盐水输移扩散特征在近十几年发生了较大变化:工程后，渤海湾平均盐度增大0.203，平均温度升高了0.105℃，同时曹妃甸附近海域浓盐水输移扩散速度明显增加。增大排放口流量至12.7 m3/s，湾内最高温度为26.46℃，较2015年最高温度增加了2.72℃。本文模型可准确模拟及预测排海废水盐度、温度分布特征，为合理布置水电联产设备排放口的位置提供理论基础。

| Abstract: | A dramatic increase in the sea reclamation works around the Bohai bay since 2000 has resulted in a change in the tidal field near the engineering area, which influenced both the spatial and temporal distribution of the high temperature concentrated salt water discharged in the sea. A three-dimensional mathematical model based on the different shoreline and topographic conditions in 2000 and 2015 was established to stimulate the high temperature concentrated salt water discharged in the sea by three power plants along the Bohai Bay. The results of stimulations show that great changes have taken place in the characteristics of both the tidal filed and the transport and diffusion of high temperature concentrated water in the Bohai Bay during the last ten years. With the completion of the project, the average salinity of the Bohai Bay increased by 0.203 and the average temperature increased by 0.105℃, in the meanwhile both the transport and diffusion rate of high concentrated salt water in the sea area near the Caofeidian increased significantly. Given the condition the flow of the drain increased to 12.7 m3/s, the highest temperature in the bay reached 26.46℃, which is 2.72℃ higher than that in 2015. This model can accurately simulate and predict the salinity and temperature distribution of the effluent and provide the theoretical basis for the locations of outlets of the power plants. |
