In order to study the reliability of numerical analysis in the calculation of foundation compression, this paper takes the coarse-grained soil foundation of a project in Milin, Tibet as the research object, uses the mechanical parameters obtained from the large-scale triaxial test and the numerical analysis of ABAQUS software to analyze and compare the compression value and load. It is considered that the load and compression situation in the numerical analysis are relatively reliable, which comprehensively reflect the stress and strain of soil under overlying load. It can be further studied according to the change of boundary conditions in engineering application.
