A possibility of using two nonlinear phenomenological models from mechanics of materials — Neo-Hookean and Mooney—Rivlin — with the aim to take the effect of strata into account in studying the seismic hazard for building sites is considered. A correspondence of these models and experimental data under a nonlinear deformation of soils is shown. It is proposed to change the existing empirical and semiempirical models of nonlinear deformation of strata by pheno menological ones.
