Abstract

Abstract

To understand the effect of particle size gradations on mechanical properties of loose granular materials, direct shear tests of specimens with different coarse particle fractions were conducted. The stress-strain curves and shear strength were obtained in the conditions of different normal stress. The results were fitted according to the model of the BoxLucas1 stress transfer. The changes of coarse sand fractions were introduced into the model as a parameter, and a modified model suitable for the strength of loose granular materials was developed. The model could take into account influences of coarse sand fractions and normal stress, and the final calculation results were in good agreements with the experimental results, which could be used to calculate shear strength of loose granular materials.
- loose granular material,
