摘　　要：在沿海水域冷却水工程中需满足机组对冷却水水量和水质的要求,并且对水域水环境影响做出评价。文章依托大连长兴岛某电厂为背景资料,建立平面二维潮流数学模型,根据实测资料对模型进行验证。在水动力模型的基础上,选取四种典型工况,对潮汐潮流作用下的电厂排水口温排水热扩散特性进行数值模拟。根据计算结果探究温排水在水域内输运、扩散规律并预测温度场最大温升包络线分布及取水口温升,分析取排水口布置方案的合理性。The machine set met the demands of water yield and water quality in the cooling water project of coastal waters, and the assessment of the influence on water environment was made. Based on the background of the plant of Changxing Island in Dalian in this paper, the two-dimensional tide mathematical model was established, and according to the measured data, the model was validated. On the basis of hydrodynamic model, four typical con-ditions were chosen, and the diffusion feature of the cooling water of the power plant was numerically simulated un-der the action of the tide and tidal current. According to the calculation results, the rules of the transportation and diffusion of the cooling water were studied, then the envelope program of the maximum temperature rise and the tem-perature rise of water intake were predicted, finally the rationality of the arrangement schemes of water intake and drainage exit were analyzed.
