Аннотация: Radiative stress is proportional to coefficient of nonlinearity n and quadrate of Mach number (М). The record of the stresses was made using radiation of the vibrator for different experimental conditions. During the intense excitation directly under the plate of vibrator the observed values of quasi-steady radiative stresses (QSRS) (100-200 kPa) correspond to unloading of preliminary loading of the soil. The initiation of quasi-steady deformations of day surface under intense excitation by vibrator is recognised in experiments on measuring a inclination of day surface near working vibrator. This additional inclination disappears at lockout of vibrator. The nonlinear seismic effects are found by Aptikaev according to the Feynman equation describing nonlinear response of absorbing medium. In geological media irrespective of the mechanism of absorption the sufficiently strong seismic waves leads to production of the QSRS.
