Application and Automatic Monitoring and Analysis of Hybrid Support Structure in Ultra-DEEP Foundation Pit Engineering in the Lanzhou Area under Complex Environmental Conditions

This paper takes the deep foundation pit project of Lanzhou Hospital Traditional Chinese Medicine as background. The design and construction is relatively difficult due to complex environment around pit, dense surrounding buildings, underground soil layer influence groundwater on pit. In order detect problems in process, was monitored real time through an automated monitoring system for whole process excavation backfilling analysis actual data shows that: (i) support scheme bored pile + prestressed anchor cable combined with concrete corner bracing can meet this type without causing disturbance buildings; (ii) case it proves that real-time measurement by robot timely safety hazards caused external factors during a very important one pits pits. provides good reference projects environments.
