In comparison with other basic mechanical properties of soils, Poisson's ratio is regarded as an elastic constant considerably underestimated. However, there is a significant number of diverse areas in which a proper knowledge of Poisson's ratio or even estimation of its value is required [6]. This article contains: definition of Poisson's ratio with distinction between static and dynamic, the values of Poisson's ratio for various materials, simple formulas how to receive this property as well as its applications in soil mechanics. Moreover, two techniques, an uniaxial loading test and resonant column test, as these which help us to determine the value of Poisson's ratio are briefly presented here. A special emphasis was placed on the second procedure of finding Poisson's ratio, which means measurements of wave velocities, longitudinal and shear one, from seismic data. On the basis of the latter methods, laboratory experiments were performed and some exemplary results were included. The obtained results display the received values of Poisson's ratio and the relationships between Poisson's ratio, elastic modules as well as velocities of elastic waves.

Key words: Poisson’s ratio, resonant column tests, natural cohesive soils.
