CONSTRUCTION MONITORING ANALYSIS OF A SUPER LARGE AND ULTRA DEEP ADJACENT SUBWAY FOUNDATION PIT PROJECT IN SHANGHAI
Excavation monitoring is of great significance for monitoring the foundation pit enclosure system and surrounding environment,conducting information-based construction,and verifying design parameters.Taking the monitoring of the foundation pit of a super large and ultra deep adjacent subway project in a certain business dis-trict of Shanghai as an example,a reasonable monitoring plan is set up to analyze the changes and causes of moni-toring data.By monitoring and warning potential safety hazards during the construction process,construction quality and progress can be effectively improved,providing reference for similar projects.
