摘　　要：针对峡湾湾口防波堤建设面临的水上作业空间狭窄和通航保障难度大的问题,以某防波堤工程为例,通过分析双口门平面布置方案及结构特点,采用水下平升法分层向上、水上端进法全面推进的水陆结合抛填成堤施工工艺,以及合理的通航管控措施。经工程实践,解决了施工难题,确保项目的顺利实施。研究结果表明:与突堤式设计相比,双口门布置的岛式防波堤在提升通航效率和保持湾内水体自净方面更具优势,可为类似工程提供参考。To the problems of narrow water operation space and difficult navigation guarantee faced by the construction of breakwater at the mouth of the fjord.Taking a breakwater project as an example,this paper analyzes the plane layout plan and structural characteristics of the double door,adopts the construction technology of water and land combined with throwing and filling into embankments,which is comprehensively promoted by the underwater lifting method and the water end entry method,as well as reasonable navigation control measures.Through engineering practice,the above construction problems are solved to ensure the smooth implementation of the project.The research results show that compared with the design of a protruding breakwater,the island breakwater with double door layout has more advantages in improving navigation efficiency and maintaining self-purification of the water in the bay,which can provide reference for similar projects.
