SEISMODYNAMICS OF UNDERGROUND PIPELINES UNDER VISCOUS-ELASTIC-PLASTIC INTERACTION WITH SOIL

摘要

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 in the "pipe-soil" system under boundary conditions of rigid fixing or free displacement Patterns of changes in displacements and stresses in pipeline sections under seismic impact in the form of a sinusoidal wave running along the axis of the pipe are determined.
