船闸水域围堰、基坑围护一体化研究

Research on Integration of Foundation Pit Bracing and Cofferdam in Ship Lock

上海国际航运服务中心项目船闸工程跨黄浦江驳岸两侧,为保障船闸在施工期间的安全,采用在陆域设置基坑围护、水域设置围堰的方法,并将围堰和围护进行有机结合,形成一个整体。该方法综合不同结构的受力工况进行分析研究,有效促成陆域围护与水域围堰共同承担挡土和止水的功能。

The ship lock of Shanghai International Shipping Service Center project is constructed across Huangpu River, to ensure the safety construction; the foundation pit and cofferdam are set in land area and water area respectively, which are organically combined into an integrated system. Diversified strain conditions of the integrated system are researched to effectively improve the performance of soil retaining and water stop of foundation pit and cofferdam to ensure the safety during the construction of the project.
