This paper comprehensively examined a variety of modeling methods and,using geological exploration drilling data and geological profile data,established a geological model based on discrete smooth interpolation theory,thereby providing an accurate geological model for the engineering support design and construction.Also,based on the design and construction case of the pile-plate support structure for deep foundation pit,structural stress analysis and support optimization were conducted.By simulating the influence of the construction process of the foundation pit on the adjacent track structure,this paper hopes to effectively guide the design of the foundation pit and the protection of the adjacent track.The integrated implementation of design and construction method for supporting structures based on the geological model can clearly and accurately express complex geological conditions and geological structures,reduce errors and omissions in the support design process,provide data support for the supporting structure design,and improve the design efficiency.Additionally,it can visualize and digitally display the spatial relationship of each layer,provide intuitive and accurate judgment for the project construction to the greatest extent,ensure the construction accuracy of the supporting structure,and improve the controllability over project cost and safety.
