Comparative study of data from geotechnical field penetration tests on sandy subsoils

Abstract

The main objective of the work reported in this paper was to compare standard penetration test (SPT), dynamic probing (DP) and cone penetration test (CPT) data for uniformly graded sandy soils located in the southeast Brazilian coastal region of Grande Vitória, Espírito Santo (GV-ES). Previously reported datasets of laboratory and field penetration test data concerning the variations of some soil parameters associated with the investigated correlations were also evaluated. The correlations analysis addressed the influences of textural characteristics, especially grain size distribution, and relative density on the obtained CPT–SPT and DP–SPT linear correlations using a newly compiled experimental database for GV-ES sands and the previously published datasets. Correlations were determined using statistical inference, specifically by simple linear regression and analysis of residues for several groups of experimental data.
