ЭКСПЕРИМЕНТАЛЬНОЕ ИССЛЕДОВАНИЕ ВЗАИМОДЕЙСТВИЯ БЛИЗКОРАСПОЛОЖЕННЫХ ПОЛОСОВЫХ ФУНДАМЕНТОВ НА СЛОИСТОМ НЕСВЯЗНОМ ГРУНТЕ Experimental study of interference between adjacent footings on layered cohesionless soil.
Аннотация
Анализируются результаты совместной работы двух близко расположенных полосовых фундаментов на слоистом песчаном основании. Исследования проводились на лабораторных моделях. Коэффициенты эффективности определялись как отношение несущей способности либо осадки при разрушении для изолированного фундамента к таким же показателям, полученным в присутствии второго фундамента. В зависимости от условий значения коэффициентов варьировались в диапазоне от 1 до почти 3, что подтверждает вывод о значительном повышаении несущей способности отдельного фундамента в присутствии второго и зависит от расстояния между ними, а также от толщины и прочности верхнего слоя.
