The majority of shallow formations in the low Veneto plain (Italy) range from medium-fine sand to silty clay of medium-low plasticity. Due to their alluvial origin these soils frequently appear interbedded with each other, and consequently an estimation of their geotechnical properties requires expensive in situ and laboratory investigation.

Abstract
The majority of shallow formations in the low Veneto plain (Italy) range from medium-fine sand to silty clay of medium-low plasticity. Due to their alluvial origin these soils frequently appear interbedded with each other, and consequently an estimation of their geotechnical properties requires expensive in situ and laboratory investigation. Moreover, the calibration of tools for CPTU data interpretation has been generally carried out for prevalently cohesive or granular soils with particular features of homogeneity. In this paper the reliability of the most frequently used relationships for CPTU tests interpretation in estimating the soil profile and geotechnical parameters on two sites is critically examined.
