Evaluation of piezocone characterization in deltaic deposits

At the Port of Ploce, situated in the river Neretva delta at south Adriatic coast of Croatia, intensive building activities are undertaken. Comprehensive and massive geotechnical investigations are needed for different structures, including drilling, laboratory testing on samples, and in situ penetration testing. Soft soil prevails in first 40 m of foundation soils. Since the quality of undisturbed samples was not satisfactory, in situ tests were used as a source for parameters for geotechnical design. CPTU, DMT, SDMT and VT tests were performed over the area. It was necessary to correlate shear strength and moduli obtained by different tests, in order to complete data for specific locations where only some testing was conducted. Useful correlations and good agreement in predicting undrained strength and moduli are shown in this paper, confirming the power of in situ tests in characterizing geotechnical properties of soft soils.
