摘要
结合合武铁路武汉枢纽江岸特大桥实例,介绍扩大明挖与钢板桩围堰相结合的超深基坑开挖施工技术,并对钢板桩围护结构的设计进行理论分析,以确保超深基坑开挖施工安全,为类似工程提供有益借鉴。
With the Wuhan Pivotal Jiangan Mega Bridge of the He-Wu Railway as a practical example, the technique of expanded open cutting in combination with steel plate cofferdam for extra-deep foundation pits is presented in the paper, with the design of the steel plate inclosing structure theoretically analyzed to ensure the construction safety of the excavation of extra-deep foundation pits. It may serve as a useful reference for other similar projects.
