Design and construction process monitoring analysis of deep foundation pit support——Taking Fujian Children's Hospital(Regional Children's Medical Center)as an example
Taking the Fujian Children's Hospital(Regional Children's Medical Center)project as an example,this paper introduces the de-sign of foundation pit and drainage measures based on the characteristics of the deep foundation pit.The horizontal displacement of deep soil,the horizontal displacement and settlement of foundation pit slope top,the internal force of support piles,groundwater level,surround-ing buildings and ground surface were monitored during construction process.The monitoring data shows that the excavation of the founda-tion pit has relatively small impact on soil displacement,groundwater level and surrounding environment.The observation data of each mo-nitoring item is within the design warning value during the monitoring period,thus ensuring the safety of construction operations.This case can be used as a reference for other similar projects.
