Аннотация


Строительство тоннелей в слабых грунтах вызывает сдвиги в существующих структурах вокруг тоннеля. Приведены результаты исследования осадки грунта, вызванной продолжением строительства Линии 7 Тегеранского метро, и сравнение данных, полученных с использованием эмпирических методов конечно-разностной 3D модели.
