摘　　要：针对双侧紧邻地铁的超大型深基坑群坑开挖工况,在原有设计意图的基础上,对分坑的施工流程顺序进行了优化。在确保周边环境保护和基坑安全的前提下,同时对分坑顺序和开挖条件进行了修改,以期压缩群坑施工工期,提高施工效率。总结的经验可为类似的群坑工程的设计深化、施工控制提供一定的借鉴。Based on the original design intent,the construction sequence of sub-pits was optimized for the excavation condition of the super large deep foundation group pits adjacent to the subway on both sides.On the premise of ensuring the environmental protection of the surrounding area and the safety of the foundation pits,the sequence of sub-pits and excavation conditions were modified at the same time,in order to compress the construction period of the group pits and improve the construction efficiency.The summarized experience can provide certain reference for the deepening design and construction control of similar group pits projects.
