SMALL-STRAIN DYNAMIC CHARACTERIZATION OF CLAYEY SOIL

Keywords: small-strain stiffness, laboratory tests, resonant column apparatus
Abstract: An appropriate evaluation of dynamic soil properties is important for proper seismic response analysis and soil modelling programs. The primary aim of this study was to investigate the dynamic properties of clayey soil from Warsaw area, taking into consideration some of the selected factors affecting the shear modulus (G) and the damping ratio (D) of examined samples. A series of resonant column tests were conducted to study the effect of applied pressure and shear strain amplitude on soil stiffness and its damping properties. These parameters were reviewed, investigated and discussed. On the basis of the results obtained from these tests as well as the theoretical analysis, it can be established that confining pressure and the range of considered strain had a significant influence on the dynamic shear modulus and on the dynamic damping ratio. The impact of stress level on D is also discussed.
