ФИЛЬТРАЦИОННЫЙ РЕЖИМ И УСТОЙЧИВОСТЬ ГРУНТОВОЙ ПЛОТИНЫ ПРИ СРАБОТКЕ ВОДОХРАНИЛИЩА
Основное содержимое статьи
Аннотация
Рассматриваются результаты численных исследований фильтрационного режима и устойчивости грунтовой плотины при сработке водохранилища. Решается задача неустановившейся фильтрации в однородной земляной плотине. Определяются параметры фильтрационного потока: положение депрессионной поверхности, величины и направление фильтрационных градиентов и скоростей потока. Дается анализ изменения максимальных градиентов фильтрации и вероятность возникновения фильтрационных деформаций. Проведены расчеты по оценке устойчивости верхового откоса на этапах сработки водохранилища с разной скоростью. Показано, что плотина, имеющая большой запас устойчивости при наполненном водохранилище, может потерять его и быть разрушенной в процессе сработки. Сделаны выводы о необходимых мероприятиях по обеспечению надежности и безопасности при эксплуатации сооружения.
