Аннотация


Статья посвящена исследованию деформационных характеристик грунтового основания, армированного геоячейками. Была проведена серия динамических трехосных испытаний, где в качестве изменяемых факторов рассматривались динамическое напряжение, всестороннее давление обжатия, процентное содержание воды в грунте и расстояние между геоячейками. В качестве испытываемого грунта использован реальный илистый песок из основания насыпи на шоссе в уезде Ронг, г. Цзыгун (провинция Сычуань, Китай). Авторами создана модель прогнозирования деформаций армированного грунта на основании известных решений Буссинеска и получены формулы для расчета осадки насыпи земляного полотна.
