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

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.
