ОСОБЕННОСТИ ПОВЕДЕНИЯ СВАЙНЫХ ГРУПП НА ГРУНТОВОМ ОТКОСЕ ПОД ДЕЙСТВИЕМ ГОРИЗОНТАЛЬНОЙ НАГРУЗКИ Non-linear response of group piles under static lateral load in sloping ground

Sivapriya S V, Shailesh R Gandhi

Аннотация


Исследуются особенности поведения свай и кустовых свайных фундаментов, расположенных на бровке грунтового откоса (склона) при действии горизонтальной нагрузки. Исследования выполнены в лотках с глинистыми грунтами различной прочности на сдвиг (30 и 50 кПа) путем статических испытаний моделей свайных кустовых фундаментов на горизонтальную нагрузку. В процессе испытаний измерялись горизонтальное перемещение фундамента и изгибающие моменты в моделях свай. Испытывались кусты свай с разным шагом, установленные на самом гребне откоса с уклоном 1:2 и на разных расстояниях от него. По мере приближения свай к склону, максимальный изгибающий момент увеличивался, поскольку пассивный клин становился меньше. Предложено соотношение для расчета несущей способности группы свай в горизонтальном направлении в зависимости от расстояния до склона.
