南昌地铁车站深基坑围护结构变形监测分析

Monitoring Analysis of Deep Foundation Pit Retaining Structure in Nanchang Subway Station

基于南昌市地铁一号线珠江路车站深基坑开挖时的时空效应以及基坑开挖与支护顺序,对基坑实际监测数据进行了分析研究,重点探讨了基坑开挖时围护结构变形规律及影响因素。结果表明,该基坑工程的设计及施工方案合理,具有安全可靠、施工简便的特点,可供类似深基坑工程信息化施工提供参考依据。

Based on the engineering background of deep excavation of Zhujiang subway station of Nanchang Railway Line 1,the time-space effect and excavation and supporting of deep foundation pit,the actual monitoring data of foundation pit was studied.Detailed analysis of the foundation pit excavation of retaining structure deformation law and influencing factor was made.The result shows that the design and construction scheme is reasonable and safe and reliable and simple in construction.The research result is useful to the design and excavation of the similar deep foundation pit project.
