摘　　要：本文针对潍坊港中港区的潮流动力和航道回淤问题进行了研究。首先概述了潍坊港的地理特征和航道现状,随后建立了二维潮流泥沙数学模型,采用Mike21 FM模块进行计算。模型验证显示,模拟结果与实测数据吻合良好,满足技术规程要求。计算结果表明,工程实施后,港区涨落潮流态基本保持一致,流速在港内逐渐减小。航道内最大横流受防沙堤影响,口门处流速最大。泥沙淤积分析指出,航道内淤积峰值出现在口门外约1 km处,最大年淤积厚度为1.84 m,港池内年平均淤积厚度为0.10 m。在大风骤淤情况下,航道和港池的淤积厚度有所增加。研究为潍坊港中港区的建设提供了科学依据,对类似港口的航道维护和防沙措施具有参考价值。This study investigates the tidal dynamics and channel siltation issues in the Gangzhong harbour district of Weifang port.It begins with an overview of the geographical characteristics and current channel conditions of Weifang port,followed by the establishment of a two-dimensional tidal and sediment mathematical model,calculated using the Mike21 FM module.Model validation indicates that the simulation results match well with the measured data,meeting the technical specifications.The results indicate that after project implementation,the flood and ebb tidal states in the port area remain basically consistent,with flow velocity gradually decreasing within the port.The maximum transverse current within the channel is influenced by the sand barrier,with the highest velocity at the port entrance.Sedimentation analysis shows that the maximum sedimentation peak occurs approximately 1 km outside the port entrance,with a maximum annual sedimentation thickness of 1.84 m,and an average annual sediment thickness of 0.10m within the harbor basin.Under strong wind conditions,sedimentation thickness increases in both the channel and harbor basin.This study provides a scientific basis for the development of the Gangzhong harbour district of Weifang port and offers valuable insights for channel maintenance and sand control measures in similar ports.
