Abstract:

Through the resonant column test on such 6 sorts of typical soils such as mud, muddy soil, silty caly, silty clay and silty sand interbedded strata, silt and residual soil, the influences of confining pressure and soil property on dynamic shear modulus G and damping ratio ? of the 6 typical soils have been 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 6 sorts of typical soils in Fuzhou area are presented. Besides, the influence patterns of the average curve parameters for G/Gmax and ? /?max of such 6 soils with the change of ? are also quantified. The above findings would be used as reference for practical projects.

Key words: typical soils in Fuzhou area, dynamic shear modulus, damping ratio, resonant column test, confining pressure
