Abstract

Dynamic shear modulus in marine clay containing sand was tested using RCA resonant column test system produced by GDS Company of UK. At the same time, comparing to the dynamic shear modulus in pure sand sample, the various factors such as the consolidation pressure, initial compactness, clay content, etc. influencing the maximum dynamic shear modulus of soil were studied systematically.The results show that the maximum dynamic shear modulus increases along with the effective consolidation pressure increasing and the initial density increasing, while it decreases along with the clay content increasing.

Key words

resonant column test / clay / maximum dynamic shear modulus / skeleton void ratio
