摘　　要：以上海某两个相邻地块基坑工程为载体,从基坑围护设计及施工角度,研究土方错层开挖在相邻深基坑工程中的应用效果。采用有限元模拟分析错层开挖对基坑围护变形影响,并结合基坑开挖实施过程总结出土方错层开挖施工的相关施工要点及经验,以期为今后类似工程提供一定的借鉴。Taking the foundation pit project of two adjacent plots in Shanghai as the carrier,the application effect of earthwork staggered excavation in adjacent deepfoundation pit project is studied from the perspective of foundation pit support design and construction.Finite element simulation is used to analyze the effect of staggered excavation on the deformation of foundation pit support,and the relevant construction points and experience of earthwork staggered excavation construction are summarized in the process of foundation pit excavation implementation,to provide some reference for similar projects in thefuture.
