Steady-state seismic vibrations of a buried pipeline in a viscoelastic soil

Аннотация

Steady-state coupled longitudinal vibrations of a buried pipeline and a viscoelastic soil during an earthquake are studied. Using specific examples of soils described by the Kelvin–Voigt model and by the viscous liquid model, the main qualitative and quantitative effects of viscosity on the behavior and seismic stability of metallic (steel) and concrete pipelines are clarified.
