洋山深水港区前沿施工期强淤分析

依据沉积物取样分析结果及有关资料的分析,对港区阶段强淤进行了研究,结果认为港区后方的小洋山~镬盖塘汊道封堵对地形演变的影响,主要限于码头前沿的局部范围,其地形的稳定性主要受控于主通道的水流状况,工程竣工后,主通道的涨、落潮量及水体含沙量应基本不变。

Analysis of rapid deposition in construction period of Yangshan Deep-water Harbor Area

Based on the analysis of deposited material specimen and relative data, rapid deposition of the harbor area construction is studied. The results show that the influence of blocking the branch from Xiaoyangshan to Huogaitang behind the harbor area on the seabed evolution, is mainly limited in the port front. The stability of seabed is mainly controlled by the current condition in the main passageway. And after the completion of the project, the flood and ebb tide volume and sediment concentration should be basically invariable.
