Аннотация


Исследуется влияние приразломных и удаленных от разлома подвижек грунта на оценку сейсмической устойчивости симметричной бетонной арочной плотины. Оценка сейсмической устойчивости была проведена с использованием показателя допустимой нагрузки, рассчитанного с помощью линейного анализа. На примере арочной плотины Карачи рассмотрены два различных подхода: в первом случае предполагается, что скальное основание является жестким, во втором - невесомым. Поведение плотины и её основания описывается в перемещениях, а водохранилища - на основе жидких элементов.
