ЭФФЕКТ НЕОПРЕДЕЛЕННОСТИ ОТНОШЕНИЯ ДИНАМИЧЕСКИХ МОДУЛЕЙ СДВИГА Effects of Uncertainty of Dynamic Shear Modulus Ratio for Fine Sand on Design Ground Motion

Qing Hu, Heng Li, Gang Yang, Yongjian Cai

Аннотация


На основе численного моделирования и статистики для условий тонкодисперсных слоев песка в районе Уханя, КНР, исследовано влияние неопределенности соотношения динамических модулей сдвига (из-за ограниченного диапазона используемых приборов), на прогноз перемещений грунта, учитываемый в проектных расчетах. Количественно проанализировано влияние указанной неопределенности на расчетный спектр сейсмического отклика, платформенное значение и характеристический период спектра отклика. Это исследование может служить ориентиром для анализа сейсмической реакции, а также теоретического изучения нелинейной динамики в геотехнической сейсмотехнике.
