ДИНАМИЧЕСКИЕ ХАРАКТЕРИСТИКИ И МОДИФИЦИРОВАННАЯ МОДЕЛЬ ХАРДИНА–ДРНЕВИЧА ДЛЯ ЛЕССА НЕНАРУШЕННОЙ СТРУКТУРЫ Dynamic characteristics of structural loess and its modified Hardin–Drnevich model

Аннотация


Ненарушенный лесс обладает особыми структурными характеристиками из-за уникальных условий его формирования. Приведен сравнительный анализ динамических характеристик ненарушенного, переформованного и водонасыщенного лесса на кручение и сдвиг с различными значениями давления уплотнения и содержания воды. На основе концепции комплексного структурного потенциала определены структурные показатели лесса при динамическом нагружении и их изменение при изменении давления уплотнения и содержания воды. Предложенные структурные параметры введены в гиперболическую модель Хардина–Дрневича для расчета начального модуля упругости при сдвиге и
максимального напряжения сдвига и, таким образом, получена модифицированная модель Хардина–Дрневича для лесса.
