Abstract: The constitutive relationship of soil is one of the important theories in geotechnical engineering, and the accurate description of its stress-strain relationship is the key problem of constitutive model. Based on the large-scale static triaxial test, this work studied the stress-strain relationship of two different graded gravel materials, used PPR non-hypothetical data modeling technology to model and fit the test results, and compared it with Duncan-Chang E-B hyperbolic model. The results show that PPR data modeling technology can better fit the stress-strain relationship of sand gravel under triaxial test. When the relative error between the calculated value and the test value is less than 6%, the qualified rate is more than 90%, and the maximum relative errors of deviatoric stress and volumetric strain are 13.2% and 20.9% respectively, which has higher accuracy than Duncan Chang hyperbolic model; PPR model can accurately describe the swelling characteristics of sand gravel in the process of shear, and has a good prediction function for the results of triaxial test. In this work, a data modeling method was proposed to represent the stress-strain relationship of soil. The research results provide a new idea for the description of the stress-strain relationship of geotechnical engineering materials.
