Abstract

Through the resonant column test on the 4 sorts of typical soils as mud, silty caly, silty clay and silty sand interbedded strata, residual soil, the influence of confining pressure and soil property on dynamic shear modulus G and damping ratio of the 4 typical soils was explored in detail.By means of tests and theoretical analyses, the average curves of G/Gmax and /max with the change of under different confining pressures as well as their recommended values of parameters for the 4 sorts of typical soils in Quanzhou were presented.Besides, the influence patterns of the average curve parameters for G/Gma and /max of such 4 soils with the change of were also quantified.
