Analysis of the Maximum Dynamic Shear Modulus and Particle Arrangement Properties of Saturated Soft Clay Soils

Abstract

In this paper, using the resonant column test, electron microscope observation, and microscopic structure analysis, the relationship between the maximum dynamic shear modulus and the microscopic particles arrangement of remolded clay soil was examined. Focusing on the soil microstructure, this study found that, as the effective consolidation stress increases, the soil particles are rearranged in an orientation parallel to the direction of maximum principal stress and maximum shear stress. The probabilistic entropy of the soil particle arrangement decreases, the mechanical wave velocity in the continuous medium of the soil particles increases, and the maximum dynamic shear modulus increases.
