Soil unit weight is one of the most important parameter used in all geotechnical calculus related to design process of any type of constructions. Determination of this gravimetric -volumetric data can be done through laboratory tests in firm soils, or indirectly as itderive from some in situ investigations such as Cone Penetrations Test (CPT) or as severalgeophysical investigations such as Down hole, Cross hole, Logging P-S velocities, insoils which can?t support undisturbed samples (very wet organic soils or sands). The aimof this paper was to apply and verify the viability of some of the most popularrelationships encountered in geotechnical engineering practice in a special case where alarge amount of laboratory and filed tests data are available and where the geologicalstructure provide a great variety of soil types. The results of in situ and laboratoryinvestigations are described and compared in order to provide a representativegeotechnical model of soil conditions for a realistic geotechnical model and to assign asuitable design for all kind of civil or industrial objectives. The available data enabledone to compare the unit weight profile obtained by empirical correlations based on CPTor laboratory results with geophysical survey, respectively ?suspension of P-S waves?.By comparing the mean values of all calculated ranges of soil unit weight with measuredmean values, some considerations regarding the influence of grain size distribution ofsoils and errors associated with each of the seven applied formulas are made with the aimof improving further applications of these formulas.
