THE PREDICTION MODEL OF GRADED GRAVEL RESILIENT MODULUS

摘要

According to the nonlinear characteristic of graded gravel resilient modulus, Based on the optimization of the three kinds of graded gravel as the research object, and combined with repeated dynamic triaxial test data, compared k~0 model and Uzan model, using statistical analysis software 1 stopt carries on the experimental parameters of nonlinear regression, obtained the correlative coefficient of three graded gravel resilient modulus, which is under the two models. Experimental results show that: Uzan model can more accurately reflects the nonlinear deformation behavior of graded gravel resilient, so the reliability of the regression modulus prediction equation for graded gravel is higher, can be used to forecast Chinese graded aggregate base modulus.
