Abstract
In the element test for coarse granular materials, the grain size distributions of the materials are often adjusted, in case the grain size of coarse material in the field is larger than the available maximum grain size of the laboratory test equipment. In this study, we carried out the large cyclic triaxial test to evaluate the effect of the grain size distribution adjustment on Young's modulus in small to intermediate strain level. The test results showed that the coarse granular materials with the adjusted grain size distribution underestimated Young's modulus of the original materials. The difference of Young's modulus was larger in small strain level than in intermediate strain level.
