EFFECTS OF VARIOUS PARAMETERS ON THE STIFFNESS AND DAMPING OF SOILS AT SMALL TO MEDIUM STRAINS

The results of three different dynamic laboratory studies are presented. The first study involved evaluating the effects of anisotropic stress state and inherent anisotropy on the small-strain stiffness of the soil skeleton. Compression and shear wave velocity measurements were performed on a dry remolded sand in a cubical calibration chamber. Application of a cross-anisotropic model to these measurements is also presented. The second study involved investigating the effects of confining pressure, excitation frequency, strain amplitude and number of loading cycles on the shear modulus and material damping of undisturbed and remolded soils. Combined resonant column and torsional shear equipment was used, and evaluation of material damping in shear was emphasized. The third study involved investigating the shear modulus of undisturbed and remolded specimens of cemented silty sand. In situ seismic testing also permitted comparison of field and laboratory values of shear wave velocity of the cemented sand. For the covering abstract, see IRRD 892179.
