ИЗМЕНЕНИЕ ДАВЛЕНИЯ ПОРОВОЙ ВОДЫ В ПЕРЕУПЛОТНЕННОЙ ГЛИНЕ ПРИ ЦИКЛИЧЕСКОМ НАГРУЖЕНИИ: ЭКСПЕРИМЕНТАЛЬНОЕ ИССЛЕДОВАНИЕ
Основное содержимое статьи
Аннотация
При циклическом нагружении циклическое воздействие внешней нагрузки в течение времени нагружения приводит к многократной перегруппировке частиц грунта, в результате чего частицы располагаются более плотно друг к другу, чем при статическом нагружении. Поскольку объем грунта уменьшается с увеличением количества циклов нагружения, накопленное избыточное давление поровой воды рассеивается за счет дренирования грунта. В данном исследовании представлены результаты прогнозирования поведения глины в частично дренированном циклическом плоском испытании. Результаты циклических трехосных испытаний высокопластичной морской глины были использованы для прогнозирования зависящих от времени изменений избыточного порового давления и осевых деформаций при циклическом нагружении с частичным дренированием. Исследование показало, что, когда насыщенная глина подвергается циклическому нагружению, снижение эффективного напряжения из-за создания избыточного давления поровой воды приводит к снижению прочности грунта. В долгосрочной перспективе на накопление давления поровой воды в насыщенной глине влияют различные факторы, включая величину приложенной нагрузки, ее частоту и собственные свойства грунта.
