地铁车站型钢混凝土组合柱施工关键技术

Key Technology of Steel Concrete Composite Column Construction in Subway Station

随着城市轨道交通和城镇经济的发展,越来越多的地铁车站和周边地块商业开发实行以公共交通为导向的开发(Transit Oriented Development, TOD)一体化建设模式,这样一来,地铁车站上方将会规划商业高层、裙房等,而受上盖荷载影响,普通混凝土柱满足不了工程实际需求,因而型钢混凝土组合柱应运而生。论文以深圳地铁8号线二期小梅沙站为工程背景,从设计深化、型钢柱施工的关键工序进行研究分析,提出地铁车站型钢混凝土组合柱的关键技术要点,旨在为类似项目提供参考。

With the development of urban rail transit and urban economy, more and more metro station and neighboring area business development of public transit adopt oriented development(Transit Oriented Development,TOD) integration model, in this way, commercial high-rise buildings and podium buildings will be planned above the subway station, etc.. Affected by the load of the cover, the ordinary concrete column can not meet the actual demand of the project, so the steel concrete composite column came into being. Taking Xiaomeisha Station of Shenzhen Metro Line 8 phase Ⅱ project as the engineering background, this paper studies and analyzes the key process of the steel column construction from the perspective of the deepening of design, and puts forward the key technical points of the steel concrete composite column of subway station, aiming to provide reference for similar projects.
