本文介绍了近二十五年来瑞士结合梁桥的发展,再现了结合梁桥的钢梁、桥面板和施工方法的变化过程。 减少了垂直加劲肋和联结杆件的数量,取消了纵向加劲肋和下弦联结系,钢梁简化,桥面板增厚。这一切使桥梁的“经济、美观、耐久”这三重要求达到了和谐。 This article introduces the development of Switzerland combined with the bridge in the past 25 years and reproduces the changing process of the steel beam, bridge deck and construction method combined with the bridge. Reduced the number of vertical stiffeners and coupling bars, eliminated the longitudinal stiffeners and lower chord linkages, simplified steel girders and thickening of deck slabs. All this makes the bridge of “economy, beauty, durability,” the three important requirements of harmony.
