大平岛围垦工程对航道、码头影响研究

Research on influence of Daping Island reclamation project on waterway & wharf

基于工程海域条件分析,建立了平面二维潮流泥沙数学模型。在实测资料验证良好的基础上,对大平岛围垦工程前、后的潮流、悬沙场等进行了模拟,就工程对围区附近航道、码头的影响进行了分析研究。研究表明,本工程的实施对周边海域没有大范围的根本性影响,其影响主要集中在西侧水道的局部水域,会使处于围区西侧水道的燕山热电厂煤码头及其航道等产生淤积,建议定期疏浚或采取其它工程措施。

A two-dimensional mathematical model for tidal current and sediment was established base on the analysis of the conditions of maritime space for the project. The tidal current and suspended sediment fields before and after implementation of Daping Island Reclamation Project, and the influence of the project on the waterway and wharf near the reclamation area was analyzed and researched. The research shows that this project has no large-range and fundamental influence on the surrounding sea areas, and its effects are mainly concentrated in partial areas in the west side of the waterway. Since the coal wharf and its transport waterway for Yanshan Thermal Power Plant will produce sediment deposition, periodic dredging or other engineering measures are recommended.
