摘要
在天津软弱地层和林立的建筑群间进行深基坑施工,为确保深基坑的施工安全,必须要有科学、合理及完善的施工技术。对天津地铁3号线和平路站采用盖挖逆作法的施工技术、工艺进行了深入探讨,比较了各种施工方法的优劣,提出"盖挖逆作法"施工需要进一步解决的问题,通过理论分析对施工方案进行了比选,对施工的关键环节进行了重点阐述。为今后天津地铁及更多的地下工程盖挖逆作法施工提供参考。
In order to ensure the safety during the construction of deep foundation pit in soft ground with buildings densely allocated around, a scientific, reasonable and perfect construction technology is the must. This paper discusses the construction technology and process of under-cover-reverse-buildlng method applied in the construction of Hepinglu Station on Tianjin Metro Line 3, compares the advantages and disadvantages of each construction method, proposes some issues needing further solution in construction with under- cover -reverse -building method, then, selects the most suitable construction scheme based on theoretical analysis and comparison, and describes the key construction procedures, which will provide reference for the coming Tianjin Metro projects and more underground projects to be constructed with under-cover-reverse-building method.
