ПРОТИВООПОЛЗНЕВЫЕ СВАЙНЫЕ КОНСТРУКЦИИ НА СКЛОНАХ С НАБУХАЮЩИМИ ГРУНТАМИ Effects of anti-sliding piles on the deformation mechanisms of bridge foundation in expansive soil slope

Аннотация


Представлены результаты аналитических исследований влияния температуры на фильтрационный процесс и условия замачивания набухающих грунтов, а также численных исследований воздействия противооползневых свайных конструкций на набухающих грунтах на фундаменты мостовых опор. Установлено, что на деформацию основания моста влияет не только вызванное осадками сниже-
ние прочности набухающего грунта, но и сопротивление сваи скольжению, а также пространственные ограничения. Противооползневые сваи усиливали влияние деформации склона и/или оползней на фундамент моста. Выявлены тенденции снижения этого влияния при увеличении расстояния между противооползневыми конструкциям и фундаментами опор.
