【摘要】 港池的布局会改变其周边海域水动力条件及其泥沙冲淤状况,为了进一步了解其影响程度,本文以山东日照豪迈重工临港厂区运输码头的改造工程为研究对象,利用平面二维数值模型MIKE21/3 Integrated Models,建立了潮流和波浪耦合作用下的泥沙输移数值模型,对该工程附近海域进行了波浪、潮流和泥沙输移的数值模拟。同时采用实测数据对数值模型进行了验证,数值模拟结果与实测资料拟合较好,表明MIKE21能有效地模拟运输码头及其周围海域潮流的变化过程。以日照豪迈重工临港厂区运输码头为依托,基于数值模拟结果,分析不同改造方案下的水动力条件和泥沙冲淤状况。结果表明:港池布局对水动力条件影响甚微,对地形地貌冲淤影响较大;模拟结果确定港池南向开口为最佳改造方案,为工程的规划和设计提供科学依据。更多还原

【Abstract】 The harbor layout will change the hydrodynamic conditions and the sediment transport of the surrounding areas. In this work, the numerical models of sediment transport considering wave-current interaction is developed based on the MIKE21/3 Integrated Models. The simulated results of total water depth and tidal current have a good agreement with the measured data, which reveals that the numerical model can effectively reproduce the hydrodynamic process. Based on the simulated results, the impacts of the different reconstruction schemes on the hydrodynamicand geographic environmentare analyzed and predicted. It shows that the layout of the harbor has little effect on the hydrodynamic conditions, buthas a great influence on the geomorphic environment. The numerical results also indicates that the south layout is the best reconstruction scheme and provides the scientific basis for the planning and designing of the harbor layout.更多还原
