Abstract
Purpose. The goal of this work is to study the properties of structurally heterogeneous geological mediums by the example of Meotian sediments which form landslide areas of the Odessa coast. Methodology. Acoustic properties of Meotian sediments were investigated in laboratory conditions by sounding of selected samples by ultrasonic pulses at different frequencies. Finding. The results of researches of physical-mechanical and acoustic properties of the samples of Meotian sediments at various depths of occurrence are given. A good co-ordination between the results of sounding rocks and their physical and mechanical properties with the results of theoretical studies of the frequency dependence of the sound velocity and absorption coefficient in heterogeneous media was obtained. The revealed anomalies have indicated that structural nonlinearities determine a character of propagation of the acoustic field in such media. Results. On the basis of analysis of changes in kinematic and dynamic characteristics of elastic wave propagation in rocks, acoustic methods are considered as the most informative ones in engineering-geological practice and in geological survey too.
