地铁车站深基坑支护特征及施工技术

Characteristics and Construction Technology of Deep Foundation Pit Support in Subway Station

伴随着我国城市化进程的加快,为构建现代化的城市交通体系,很多大中型城市都在积极进行地铁工程的建设。与常规的交通工程项目,地铁车站建设时面临的技术难度较大,因为属于深基坑作业,再加上处于交通、管网和构筑物遍布的地段,导致地铁车站基坑作业中面临着很多的技术难题,基坑开挖、支护等过程中的安全风险非常高。基于此,本文详细分析了地铁车站深基坑支护的特征,并探析了相应的施工技术,对地铁车站施工具有一定的技术指导意义。

With the acceleration of urbanization in China,many large and medium-sized cities are actively building subway projects in order to build a modern urban traffic system.Compared with the conventional traffic engineering projects,the subway station construction is faced with great technical difficulties,because it is a deep foundation pit operation,and it is located in the section where traffic,pipe network and structures are all over,resulting in subway station foundation pit operation is facing many technical problems,and the safety risk in the process of foundation pit excavation and support is very high.Based on this,this paper analyzes the characteristics of deep foundation pit support of subway station in detail,and explores the corresponding construction technology,which has certain technical guiding significance for the construction of subway station.
