Abstract

The paper presents proposals for the assessment of subsoil stiffness based on results of the seismic cone penetration test. Correlations between penetration parameters and constrained modulus were determined for three genetically different groups of cohesive soils. For the analyzed soil material quantitative estimation was also conducted for the parameter, which determines the relationship between the constrained modulus and initial shear modulus. A marked trend was shown for this parameter with the soil behavior type index used in the classification of soils in the cone penetration test.
