在对国内外有关软土地区基坑变形特性调研的基础上,通过对软土地区地铁车站基坑变形特性的统计分析,结合苏州地区地铁基坑变形的设计值进行讨论,总结苏州典型基坑的变形特征量和变形规律。采用数值方法和经验分析研究研究苏州轨道交通一号线地铁车站基坑支护结构和周边土体的变形性状和相关影响因素,总结主要控制措施并分析不同措施的控制效果,提出苏州轨道交通地铁地下车站基坑施工变形控制措施建议。
在理论分析的基础上,针对苏州轨道交通一号线东环路站的施工难点,提出施工关键技术与实施方案,确保工程的顺利完工。
The mechanical mechanism, excavation deformation characteristic and control methods were studied in this paper during the construction of Suzhou urban subway station excavation.
Based on lots of papers on the pit deformation characteristic analysis in soft soil areas in home and abroad, paper made a statistical analysis of the pit deformation, discussed conbined with the design value of the pit deformation in Suzhou rail transit, and summarized the typical pit deformation characteristic value and deformation rules.
By both numerical method and empirical analysis, it was analyzed that the deformation characters and effort factors of the support structure and surrounding soils in the line 1 rail transit in Suzhou.The results of different control methods were studied and then suggestions on the defromation controlling methods during the pit excavation construction were given.
Based on the theoretical analysis, according to the difficulty in the construction of the Donghuan station in the line 1 rail transit of Suzhou, it put forward some key construction technologies and implementing scheme in order to ensure the safety of the project
