Monitoring study of Guang'anmen Hospital outpatient building foundation pit excavation

Monitoring is playing an important role on the building under construction (especially in deep foundation construction phase). By professional, scientific and timely monitoring, reliable monitoring data and information on security incidents that may occur can be provided timely. In this paper, Guang'anmen Hospital outpatient building foundation pit project was analyzed. The horizontal displacement at the top of supporting structure and settlement of the surrounding buildings were discussed. The results show that the horizontal displacement and the impact on surrounding buildings is within a permissible range, which entailed the safety of the foundation pit.
