    Abstract
  • Based on the geotechnical investigation and monitoring data of Jishuitan Hospital project of deep foundation pit supporting, a three-dimensional excavation model by MIDAS GTS was used to simulate the deformation of adjacent buildings caused by deep excavation during construction. To verify the reliability of MIDAS GTS software applied in engineering, earth pressure, horizontal displacement of support structures, and settlement of surrounding buildings were monitored. The reliability of the numerical simulation analysis and calculation results was verified by comparing the data obtained from the 3D model simulation with actual monitoring data. The research results indicate that numerical simulation analysis can serve as an auxiliary means for the design and scheme comparison of foundation pit support, and can provide reference for the layout of foundation pit monitoring points.
