Taking a large-scale deep foundation pit project in Guangzhou financial city as the research background, the construction process of the foundation pit is analyzed by the finite element software Midas GTS-NX. The simulated results are compared with the monitoring data, and the surface settlement deformation of the foundation pit and the horizontal displacement of supporting piles are compared and analyzed. Although the comparison results are different, the overall change trend is the same and the data are similar, and within the range of engineering deviation, the results show that the numerical simulation can provide reference for foundation pit deformation monitoring scheme design and construction scheme design.
