天津某海堤工程对水动力环境影响数值模拟

摘要

运用MIKE21建立潮流数学模型,计算评价海域潮流场现状,可准确的预测工程建成后的潮流场分布,对工程可行性做出评价,为工程应用提供完备、有效的设计参数.在天津某海堤工程中,通过与研究区域多个站位的实测结果对比显示,计算域潮流场预测结果较为合理,总体上看,该工程的建设仅对局部位置处的水动力产生了影响,而对工程周边水域的影响微小,对该海域的水流流态影响也很小,说明该工程的建设是可行的.%Using MIKE21 established the tidal current mathematical model to calculate the tide field situation of evaluation sea,can accurately predict the trend of the field distribution after the completion of the project.To make evaluation of the project feasibility and provide comprehensive and effective design parameters for the engineering application.In the project of the outer shore protections in Tianjin,through compared with the measured results of the multiple sites in research area,showed that the prediction result of tidal current field in calculation domain is reasonable.On the whole,the construction of the project only has an effect on the hydrodynamic in local location,and the influence on surrounding engineering waters is small,the effect on the flow regime of the area is small,too.The construction of the project is feasible.
