    STUDY OF SOIL-ROCK MIXTURE STRESS RELAXATION TEST

    • The stress relaxation test of soil-rock mixtures of 20%, 30% stone-containing under triaxial compression is carried out on the strain triaxial apparatus by step loading method.According to the results, divide the stress relaxation stage of soil-rock mixtures, the stress relaxation characteristics under different stone containing were analyzed and compared. Studies suggest that, with the increase of axial stress, the stress relaxation increases, the stress relaxation ratio decreases. Wiechertmodel can describe stress relaxation characteristics of soil-rock mixtures, theoretical curves fitting with the experimental curve is very good.
