РАЗВИТИЕ ОПОЛЗНЕВЫХ ПРОЦЕССОВ ВО ВРЕМЕНИ ПОД ДЕЙСТВИЕМ СЕЙСМИЧЕСКИХ НАГРУЗОК TIME-HISTORY ANALYSIS OF SOIL SLOPE SUBJECTED TO SEISMIC LOADINGS

PRAGYAN PRADATTA SAHOO, Sanjay Kumar Shukla

Аннотация


Проведено исследование поведения когезионно-фрикционного склона во времени при сейсмическом воздействии с использованием записей землетрясения 1995 г. в Кобе. Разработана двумерная динамическая конечно-элементная модель в условиях плоской деформации с использованием упругопластического критерия Мора-Кулона. Проведен совместный анализ максимальных горизонтальных и вертикальных сейсмических ускорений у основания склона. Полученные результаты показывают, что вызванное комбинированными сейсмическими нагрузками смещение склона больше по сравнению со случаем только горизонтального нагружения. Кроме того,
ожидается, что разрушение начинается у носка склона раньше, чем на гребне.
