The paper presents the results of seismoacoustic studies of soils on the example of samples of unsalted Sarmatian clays from the Northern black sea region. Samples of natural addition and humidity, as well as corresponding samples of soil particles were studied. Regression dependences of the longitudinal wave velocity on some indices of physical and mechanical properties of Sarmatian clays are revealed. The values of elastic wave propagation velocities determined as a result of ultrasonic investigations are used to calculate the increment of the seismic score and to map seismic microzoning, which is extremely important for ensuring the safety of construction in seismic areas. The obtained results can be used for seismic microzoning of any areas composed of clay swollen soils.
