In order to ensure the stability of foundation pit excavation,this paper takes the deep foundation pit of a large commercial building as the research object,analyzes the support design principles,compares different support schemes by using expert consultation method,and finally selects the"bored pile+bolt"support scheme.Subsequently,the three-dimensional model of the foundation pit was established by Midas/GTS software,and the deformation of the foundation pit under different working conditions was analyzed to verify the feasibility of the support scheme,and the research results could provide theoretical guidance for the design of similar foundation pit projects.
