Аннотация


Цель исследования состояла в определении влияния количества воды в трубопроводе на реакцию трубопровода и окружающего грунта при сейсмической активности. Проведены испытания на вибро-стенде и проанализированы реакция грунта и трубопровода на ускорение, а также трубопровода на деформацию. Для волн Кобе и Эль-Сентро коэффициенты усиления поверхностного ускорения при за-
полнении водой четырех пятых объема трубопровода снизились на 20,59% и 14,63% по сравнению с состоянием трубы без воды. Показано, что при проектировании подземных трубопроводов на сейсмическое воздействие уровень жидкости внутри трубопровода является критическим фактором, требующим тщательного изучения.
