Deformation analysis of the exterior-protected construction through deep foundation ditch excavation in one station in Nanjing city

Combined with the deep foundation ditch construction in one station in Nanjing city,it introduces the design principles of this project monitoring system,analyzes the monitoring data of this project based on the comprehensive considerations to the design,construction safe and environmental protection,researches the exterior-protected construction deformation,and brings forward the measures reducing the exterior-protected construction deformation,which will supply engineering reference to the similar projects.
