| 摘 要： | 天津南港工业区位于渤海湾典型的淤泥质海岸,其港区为环抱式有掩护的平面布局,规划建设10万吨级航道。为准确预测港池航道的泥沙回淤状况,采用双向嵌套网格建立波浪潮流共同作用下的泥沙运动数学模型,考虑波浪辐射应力作用,以及波浪引起的紊动和波浪增强海床底部切应力对悬沙输移的影响。模型选取现场实测大潮作为代表潮,以工程海域附近测波资料的能量加权平均结果作为代表波,对邻近的天津港15万吨级航道年均回淤进行了验证,确定数学模型中相关泥沙运动与底床冲淤的计算参数。在此基础上,数学模型预测了南港工业区规划的港池航道总的年均回淤量,与天津港主航道资料类比,计算的南港工业区港区10万吨级航道泥沙回淤分布与淤积总量是合理的。

| Abstract: | Tianjin Nangang Industrial Zone (TNIZ), located in the typical muddy coast of Bohai Bay, is planning to construct a port with a 105 DWT entrance channel. To predict the siltation in the basin and the channel of the port, a two-way nested grid numerical model is established to compute suspended sediment transport with wave-current interaction, considering wave radiation stress, wave turbulence, wave enhanced bottom shear stress and their effects on sediment transport. Measured spring tide and velocities are selected as representative current conditions in the model, and energy-weighted-average wave data represent wave conditions. Annual siltation in the 1.5×105 DWT channel near the Port of Tianjin is used to verify the model. On this basis, the numerical model predicts the annual siltation in the entrance channel of TNIZ and the results are credible in comparison to the data observed in the waterway of the Port of Tianjin. |
