自锚式悬索桥是一种将主缆锚固在自身加劲梁上的桥式结构,因其跨越能力强,优点比较突出,因而得到了越来越广泛的应用。在跨度较大且跨越通航河流或深谷时,自锚式结合梁悬索桥如果仍采用传统方法施工,将会导致临时设施多、工期长、造价高等问题。本文提出一种先缆后梁的施工方法,具有良好的科学性、适用性和经济型。 Self-anchored suspension bridge is a kind of bridge structure which anchors the main cable on its own stiffening girder. Because of its advantages of overchanging ability and prominent advantages, it has been more and more widely used. In the span of large and across navigable rivers or deep valleys, the self-anchored composite beam suspension bridge if the traditional method of construction is still used, will lead to temporary facilities, long construction period, high cost. This paper presents a construction method of cable-back beam, with good scientific, applicability and economy.
