Abstract

Estimation of Vs from other testing indices has gained increasing interest over the decades. The enhanced seismic piezocone penetration testing (SCPTU) provides a convenient method to measure Vs simultaneously with other three indices including the cone tip resistance, sleeve frictional resistance and pore water pressure in a close proximity. In this study, a database containing 612 sets of data points is compiled for the stress-normalized SCPTU parameters of the Jiangsu cohesionless soils. An approach based on the multivariate distribution method is utilized to develop the multivariate correlations among the normalized shear wave velocity (Vs1) and other three indices. It is shown that the correlations are reliable to describe the dependence of the Vs1 on other three indices for the Jiangsu cohesionless soils. However, caution shall be taken when these correlations are applied in other soils.
