通过对苏州火车站地铁2号线基坑工程的分析,围绕时空效应理论,介绍了采用＂分区、分层、分段、对称、平衡＂的开挖方法,并且具体阐述了基坑开挖的施工顺序和施工方法,同时介绍了相关的技术措施,通过合理确定支撑体系、综合控制基坑变形等措施,以保证深基坑的顺利开挖,确保了基坑稳定及周围建筑物和管线的安全,为同类工程的施工提供了一种新的思路。
通過對囌州火車站地鐵2號線基坑工程的分析,圍繞時空效應理論,介紹瞭採用＂分區、分層、分段、對稱、平衡＂的開挖方法,併且具體闡述瞭基坑開挖的施工順序和施工方法,同時介紹瞭相關的技術措施,通過閤理確定支撐體繫、綜閤控製基坑變形等措施,以保證深基坑的順利開挖,確保瞭基坑穩定及週圍建築物和管線的安全,為同類工程的施工提供瞭一種新的思路。

Through analyzing foundation pit engineering of subway No.2 line of Suzhou railway station,based on space-time effect theory,the paper introduces the excavation method of ＂sub-region,sub-layer,sub-section,symmetry,balance＂,specifically describes construction procedure and construction methods of foundation excavation,and introduces relevant technological measures.Through rationally determining support system and comprehensively controlling foundation pit deformation and other measures,it guarantees the smooth excavation of deep foundation pit,ensures the foundation pit stability and the security of surrounding buildings and pipeline,which has provided a kind of new idea for similar engineering construction.
