The article provides research on assessing the degree of influence of inertial forces in solving problems of seismodynamics of underground polymer pipelines. An applied calculation program was developed using the finite difference method. Dangerous points of maximum normal stresses occurrence under the influence of seismic loads on an underground polymer pipeline were determined, considering the viscoelastic interaction in the "pipe-soil" system.

В статье приводятся исследования по оценке степени воздействия сил инерции при решении задач сейсмодинамики подземных полимерных трубопроводов. Используя метод конечных разностей, разработана прикладная программа расчета. Определяются опасные точки возникновения максимальных нормальных напряжений при воздействии сейсмических нагрузок на подземный полимерный трубопровод с учетом вязкоупругого взаимодействия в системе «труба-грунт».
