| 摘 要： | 为了在大范围数学模型中合理有效地模拟码头桩基等小尺度建筑物附近的潮流场,采用非结构网格建立了渤海二维有限元潮流数学模型.在面积达85 700 km2的模型范围中将码头桩基概化为面积约20-30 m2的不透水单元,用于直接模拟桩基附近的复杂潮流场.在此基础上,对渤海曹妃甸海域10万吨级LNG(液化天然气)码头布置的走向进行了优化.结果表明:数学模型模拟的潮位和流速等水动力特征与实测结果一致,LNG码头布置的优化结果合理可信.表明建立的能够直接模拟小尺度建筑物的渤海二维有限元数学模型可应用于码头工程布置及优化的潮流场模拟研究.

| Abstract: | In order to reasonably simulate tidal currents around small structures such as piles in a large-scale model domain,a 2-D hydrodynamic integrated model for Bohai Sea is established with the finite element method.The grid can be discretionarily refined as a non-structure triangle or quadrilateral so that piers can be treated as one or several impermeable elements with an area of 20 to 30 km2 in a model domain over 85 700 km2.The computational results of tidal levels and horizontal velocities are in good agree... |
