Аннотация


С использованием конечно-элементного 3D-моделирования в программном комплексе Абакус проведено исследование влияния различных схем проходки транспортных туннелей новым австрийским методом на осадки поверхности и усилия в одиночной свае фундаментов расположенных рядом зданий. Учитывалось влияние не только последовательности, но и типа извлечения грунта в каждом туннеле. Показано, что результаты зависят от выбора схемы проходки; при этом основные эффекты наблюдаются в зоне до двух диаметров туннеля.
