潍坊港潮流分析及航道回淤预测

Tidal current analysis and channel siltation prediction of Weifang Port

潍坊港处于莱州湾的中部,岸滩水深较浅且变化平缓,泥沙运动较为活跃,泥沙淤积对航道的运营维护影响较大。通过建立潮流模型和泥沙输移数学模型进行计算,所得结果与现有的实测数据进行对比验证;再进一步模拟航道的冲淤情况,预测航道回淤分布规律以及航道沿程的淤强分布情况。结果表明,潮流模型和泥沙输移模型计算结果与实测数据吻合度均较高,预测航道年淤积量约为391.3万m^3。

Weifang Port is located in the middle of Laizhou Bay.The depth of beach is shallow and the variation is gentle,and the sediment movement is active.The siltation of sediment has a great influence on the operation and maintenance of the channel.This paper establishes the tidal current model and sediment transport mathematical model for calculation,compares the results with the existing measured data,then further simulates the scouring and silting conditions of the channel to predict the back silting distribution and the silting intensity distribution along the channel.The results show the calculation results of the tidal current model and sediment transport mathematical model are in good agreement with the measured data,and the predicted annual siltation volume of the channel is about 3.913 million m^3.
