ВЛИЯНИЕ ПОСЛЕДОВАТЕЛЬНОСТИ ВЗРЫВНЫХ РАБОТ НА СОСЕДНИЕ ЗДАНИЯ ПРИ СТРОИТЕЛЬСТВЕ СКОРОСТНОЙ АВТОМАГИСТРАЛИ Study on the influence of rock blasting sequence on adjacent buildings in Hehui Expressway

Аннотация


Исследовано влияние последовательности проведения взрывных работ в зоне строительства относительно существующей застройки «от краёв к середине» и наоборот. Численное моделирование, результаты полевых испытаний и данные о вибрационных характеристиках близкорасположенных зданий позволили дать рекомендации по последовательности проведения взрывных работ при условии обеспечения эффективности и безопасности строительства. При использовании последовательности «сначала середина, а затем край» максимальная скорость элементов существующих зданий под действием ударной волны составляет 1,1 см/с, что находится в разумных пределах безопасности.
