This paper initially compares and discusses a majority of correlations of (qc) and (??s) with typical geotechnical parameters such as relative density (Dr), the effective overburden pressure (?'v), void ratio (e), mean grain size (D50), the degree of uniformity (Cu), lateral stress (?'h), mean confinement pressure (?'m), overconsolidation (OCR), and angularity. The paper then presents the results of a series of experimental simulations for cone penetration test (CPT) on both polydisperse spherical glass beads and natural sands samples with different mechanical properties as well as different loading conditions. Stress-strain records along the soil samples are monitored during the tests. Results obtained for (qc) and (??s) are correlated with such geotechnical parameters and the corresponding graphs are plotted in order to predict the real behavior of natural soils in the field.
