Abstract We present a theoretical constructive model describing the elastic properties of a liquid-saturated granular medium with the external pressure taken into account. This model permits calculating the bulk and shear moduli, the speed of sound, the natural frequencies, and the mode shapes of acoustic pressure and vibrational velocity. The desired fundamental characteristics are determined in terms of the medium structure parameters, which is important in geophysical and technical applications. We show that the speed of sound polynomially depends on the pressure in loose media. This dependence was confirmed by numerical laboratory experiments in a wide range of pressure measurements and of the working space geometry. We separately study the case of pressure caused by the weight of the upper layers of the medium (ground). We establish some qualitative mechanical effects concerning the dependence of the elastic properties on various parameters of the medium.
