Classification and State-Parameter Assessment of Granular Soils Using the Seismic Cone

Schnaid, Fernando / Nierwinski, Helena Paula / Odebrecht, Edgar

This paper presents a methodology developed for soil classification and state parameter ( $ψ$ ) evaluation for granular soils based on seismic cone penetration measurements. The method uses a two-stage soil classification system that is first applied to categorize soil groups and identify drainage conditions. The ratio of the small strain shear modulus and the cone tip resistance $G_{0} / q_{t}$ is the basic element for soil classification that, on a subsequent stage, is combined to the state parameter $ψ$ to identify sands that potentially exhibit strain softening response upon undrained loading.
