STUDIES ON PHYSICAL CHARACTERISTICS OF SOME ROMANIAN SITES

This paper intends to present physical characteristics of sonic sites scattered throughout Romanian territory. Field measurement tests (seismic and geotechnical) were performed on these sites. The following parameters were determined seismic waves velocities (V(P), V(S)). dynamic moduli values (longitudinal, E(d) and shear, G(d)). Poisson coefficient (mu(d)) apparent density (rho(a)), lithology and layer thickness Laboratory tests on resonant columns (Drnevich) were performed on samples from almost the same sites. The shear modulus (G(d)). shear velocity (V(S)) and apparent density (rho(a)) were determined for these samples (with known lithology and depths) Results front field and laboratory tests are analyzed, compared and discussed
