Analysis of Correlations between Cone Penetrometer and Pencel Pressuremeter Parameters

PENCEL Pressuremeter and Cone Penetrometer tests were performed at two sites chosen in Florida. One of the sites was predominately clays and the second was sands. The study goal was to reveal that pushed-in PENCEL tests would produce reliable engineering parameters. The PENCEL was pushed to the preferred test depth using the cone penetrometer equipment. Correlations were developed within the engineering parameters obtained from PENCEL pressuremeter data and between the PENCEL and cone penetrometer engineering parameters. All correlations matched published values. From the PENCEL data excellent correlations were created between the initial elastic modulus and limit pressures. Excellent correlations were also produced between the initial elastic modulus and the limit pressure as well as the initial elastic modulus and the elastic reload modulus. From the comparisons between pressuremeter and cone penetrometer data, promising correlations were developed between the pressuremeter initial elastic moduli and Cone Penetrometer tip resistances. Correlations were also developed between pressuremeter limit pressure and Cone Penetrometer tip resistances.
