燕窝山陆岛交通码头工程水域平面布置

Planar water layout of Yanwoshan land-island transportation wharf project

某工程建设于岛礁地形,水域波浪掩护条件差、潮流强劲、泥沙含量高,对建设陆岛交通码头极为不利。如何掩护港池、归顺水流、减少淤积是该工程水域平面布置的重难点和关键技术问题。通过分析建港条件,结合模型试验结果提出密排桩防波堤和码头水工建筑物相结合的设计方案。该工程在建设期间经受了台风、寒潮等考验,挡浪效果明显,解决了建设难题,也为相似岸线的开发、利用提供了新的设计思路。

A project is constructed on island reefs, with poor wave cover conditions, strong tidal currents, and high sediment content, which is extremely unfavorable for the construction of a land-island transportation wharf. Therefore, the key technical difficulty in the water layout of this project is to find ways to cover the harbor basin, adjust currents, and reduce sediment deposition. Through the analysis of harbor construction conditions and model simulations, we put forward a design scheme of combining the close pile breakwater with the hydraulic structure of the wharf. During the construction of the project, the project has withstood the tests of typhoons and cold waves with good wave blocking effects. In this way, the construction difficulty is solved, and new design ideas are provided for the development and utilization of similar shorelines.
