摘要
随着城市轨道交通的快速发展,建造地铁车站的施工环境越来越复杂。以天津地铁5号线津塘路站为例,介绍了在复杂周边环境、软弱地层中盖挖逆作法施工工艺及关键技术措施。该工艺对地铁深基坑工程施工效率高、对周边环境影响较小、具有良好的社会效益和经济效益,可推广应用。
With the rapid development of urban rail transit, the construction environment of metro station is becoming more and more complex. Taking the Jintang Road Station of Tianjin Metro Line 5 as an example, this paper introduced the construction process and key technical measures of top-down excavation in the complicated surroundings and soft strata. The technology has good social and economic benefits and can be popularized and applied to the deep foundation pit engineering for its high construction efficiency and less influence on the surrounding environment.
