英文摘要	The contribution of gravel fraction on the maximum shear modulus (G(max)), dynamic shear modulus ratio (G/G(max)), and damping ratio (lambda) of cementitious coarse-grained soils has not been fully understood yet. Large-scale triaxial cyclic tests for geopolymer-stabilized coarse-grained soils (GSCGSs) were conducted with different volumetric block proportions (VBPs) under various confining pressures (CPs) for investigating their dynamic behaviors and energy dissipation mechanisms. Results indicate that the G(max) of GSCGS increases linearly with VBPs but nonlinearly with CP. High VBPs will probably result in a gentle decrease in G/G(max) and a rapid increase in normalized lambda (lambda(nor)), while the opposite is the case for a high CP. With the shear strain amplitude being normalized, the G/G(max) and lambda(nor) are distributed in a narrow band with low dispersion and thus can be well-described by empirical functions of the normalized shear strain amplitude.
