洋口港人工岛围堤钢板桩附近海床冲刷问题的处理

Measures against Seabed Erosion around Steel Sheet Pile Supporting Seawall of Yangkou Port Artificial Island

洋口港人工岛地处游荡性辐射沙洲,为保证人工岛围堤结构的稳定,围堤护底采用软体排与钢板桩相结合的型式,以形成对围堤的立体防护。在钢板桩打桩施工过程中,钢板桩周边海床的沙面出现冲刷现象,在分析海床沙面冲刷成因的基础上,重点介绍采取的多种工程措施。

Yangkou port artificial island is located at random radiating bar. To assure artificial island seawall structure, soft bent and steel sheet pile are combined and used to be seawall bottom protection, which defends the seawall three-dimensionally. Seabed surface around steel sheet piles is scoured in the construction of steel sheet pile driving. Based on the analysis of seabed surface scouring cause, a variety of measures that are adopted in the project are recommended.
