摘　　要：近年来,随着我国深基坑地连墙+钢混凝土内支撑围护结构项目的增多,钢筋混凝土支撑梁拆除成本的控制一直是决定项目盈亏的重要一环。如何能在既保证基坑安全,结构施工质量,又能快速高效低成本下完成混凝土内支撑的拆除一直是建筑施工行业的难题。本文针对武汉环球贸易中心项目三道混凝土内支撑拆除工艺进行论述,寻求一种安全、高效、快速、低成本下基坑水平支撑拆除方式。In recent years, with China＇s deep foundation pit reinforced concrete supporting the increase in the construction of the project, reinforced concrete support beam removal cost control has been an important part of the project to determine profit and loss. It is problem in the construction industry that how to ensure the safety of the foundation pit, structural construction quality, hut also fast and efficient low cost to complete the removal of steel within the support. This paper discussed the removal process of three reinforced concrete supports within the Wuhan International Commerce Centre project, and sought a safe, efficient, fast and low-cost way to remove the foundation pit.
