The invention discloses a determine method of rebound moduli of a soil rock mixture. The method comprises the following steps: dividing the soil rock mixture into a Group A1 and a Group A2; measuringa measured rebound modulus Ex of a Group P of the soil rock mixture in the Group A1 of the soil stone mixture; determining optimal micromechanical parameters of the soil rock mixture; determining a numerical test rebound modulus of a soil stone mixture after mixing the Group A2 and the Group A1; determining regression coefficients a and b in a regression equation of the rebounding modulus of the soil rock mixture; and determining the rebound modulus of the soil mixture to be tested. According to the determine method of the rebound moduli of the soil rock mixture, the rebound modulus of the soil rock mixture containing the particle size larger than 40 mm in the roadbed soil can be effectively predicted to provide accurate parameters for design of soil and rock mixed filling roadbed and improve the reliability of the design of the soil and rock mixed filling roadbed; and the method is of great significance for reducing disease incidences of the soil rock mixed filling roadbed and prolonging the service life of the road.
