摘　　要：基坑逆做法近年来在我国上海、深圳等地区已逐步应用,取得了很好的发展,目前在福建省内应用及研究仍较少。主楼顺作、裙楼逆作工法作为一种在特定条件下适用于超高层建筑地下室深基坑施工的先进工法,在对周边环境保护要求较高、施工场地狭小、对主楼节点工期要求紧迫的深基坑中,具有众多显著的优点。本文结合该工法在禹洲广场基坑工程的应用,对设计施工要点、施工工序等进行阐述,希望能对今后类似工程起到一定的参考作用。Top-Down construction in support of excavation becomes more and more popular in cities such as Shanghai and Shenzhen.However,the application of top-down construction in Fujian is in early stage.As an advanced construction method applicable to support of excavation in high rise buildings basement construction,bottom-up construction in main structure and top-down construction in annex combined with basement slab and beams used as brace has advantages on projects in which restricted surroundings and schedule of key milestones are concerned.This paper describes the design and construction of this method applied in Yuzhou Plaza,which provides insights and reference for similar projects in the future.
