Аннотация


Приводятся результаты специальных экспериментальных исследований, а также численного моделирования динамического поведения и разрушения выветрелого скального склона под действием гармонических волн с различными пиковыми ускорениями. Предлагаются количественные характеристики основных форм разрушения. Выделено четыре основные стадии разрушения: упругопластическое
деформирование; появление изолированных трещин внутри грунтового массива на склоне; взаимодействие системы трещин с образованием блоковой структуры; перемещение тела скольжения. Полученные результаты предлагается использовать для практических инженерных задач при оценке сейсмической устойчивости выветрелых скальных склонов.
