    Abstract
  • Comparative analysis of monitoring data and numerical calculation results is carried out based on a 27.4 m deep foundation pit pile-anchor supporting structure in Chinese PLA General Hospital. The results show that the horizontal displacement, the vertical displacement and deep horizontal displacement deformation of foundation pit support structure are small, which are far less than the pre-warning value specified in the code. All anchors are coordinated with each other, but the anchor bolt is far less than the pre-warning value. The maximum settlement of the surrounding road is 4.8 mm, which is far less than the early warning value of the foundation pit. The analysis shows that the design of the supporting structure selected for the foundation pit is reasonable, and the monitoring value of the supporting structure during the excavation process is in good agreement with the numerical calculation data, which can provide reference for similar projects.
