小门岛5万吨级煤码头工程潮流泥沙数模研究

Numerical modeling study of tidal current and sediment on Xiaomendao coal dock project for ships of 50 000 dwt

使用TK-2D软件对小门岛5万吨级煤码头工程进行了研究,对港池开挖后的流速变化进行了分析,对泥沙回淤强度进行了预报。研究结果表明:(1)大、小门岛围垦工程及5万吨级煤码头港区开挖工程实施后,与现状情况相比,小门水道及开挖区涨、落潮流速普遍增加;(2)在大、小门岛围垦工程基础上5万吨级煤码头港区开挖后,与大、小门岛围垦工程情况相比,小门水道及开挖区涨、落潮流速减小;(3)港区开挖后,泥沙淤积不严重,开挖后水深能够维持住。

Based on TK - 2D software, studies are carried out on the project of Xiaomendao coal dock of 50 000 dwt. The change of the average velocity is analyzed and the sedimentation strength is predicted in the excavated basin. The study results are as follows： （1）Compared with prototype, the flow speeds both at flood tide and at ebb tide are generally increase in Xiaomen waterway and the excavated basin after the reclamation project of Damendao and Xiaomendao and the excavation of the 50 000 dwt coal dock basin. （2） Compared with reclamation project of Damendao and Xiaomen- dao, the flow speeds both at flood tide and at ebb tide are generally decrease in Xiaomen waterway and the excavated basin after the excavation of the 50 000 dwt coal dock basin. （3） The sedimentation is little after the basin of the 50 000 dwt coal dock is excavated and the water depth in the basin can be kept after its excavation.
