ВЛИЯНИЕ СВОЙСТВ БОЛТОВЫХ СОЕДИНЕНИЙ В КОЛЬЦЕВЫХ СТЫКАХ НА ДЕФОРМАЦИИ ИЗГИБА ТОННЕЛЯ БОЛЬШОГО ДИАМЕТРА Influence of Tilted Bolts on Flexural Behavior of Circumferential Joints in a Large Diameter Tunnel

Аннотация


С помощью метода конечных элементов (МКЭ) анализируется продольный изгиб тоннеля большого диаметра по величине деформаций в зоне кольцевых стыков. Исследуется влияние свойств материала и угла наклона соединительных болтов на жесткость стыков при изгибе. Показано, что большую роль при определении жесткости соединений при изгибе играют нелинейные свойства и прочность материала соединительных болтов, а также угол их наклона к плоскости стыка. В частности, учет нелинейных свойств материала болтов позволяет при проектировании обделки более адекватно, в сторону уменьшения, прогнозировать раскрытие стыка при работе болта в пластической стадии.
