Mechanical characteristics of soil under static and dynamic strains are determined
experimentally. Their accuracy and reliability depends on quasi-static nature of strain …

The solution to the problems of longitudinal vibration of an underground pipeline is
considered, taking into account the linear and nonlinear viscous–elastic–plastic interaction …

Mechanical characteristics of soils under dynamic and static loads are determined in
laboratory conditions on special devices. Dynamic loads in the devices are initiated by an …

A piecewise-linear problem of the effect of a wave propagating in soil on an extended
underground pipeline interacting with soil according to the model of an" ideal elastoplastic …

The experimental diagrams between stress and strain components for soft soils are non-
linear. Nonlinear diagrams qualitatively differ for soils of undisturbed and disturbed …

The assessment of the effect of the deformability of the underground pipeline on the linear
coefficient of longitudinal shear under various boundary conditions at the ends of the …

The results of laboratory experiments on the dynamic compression of loess soil samples at a
falling weight deflectometer (FWD) are presented. From the results of the experiments …

Nonlinear laws of interaction of underground pipelines with soil are considered, based on
linear-elastic, visco-elastic laws of shear strain in soils, and Coulomb's law. Mathematical …

The purpose of this study is to develop numerical algorithms for solving seismodynamics
problems of an extended underground pipeline interacting with the ground according to the …

The article is devoted to the study of longitudinal wave propagation in a viscoelastic
medium. A mathematical model of the problem of a linear viscoelastic medium was …
