引言 装配式预应力混凝土桥梁结构在捷克斯洛伐克桥梁建设的总数中占有相当大的比重。跨度在30m以下的桥梁通常设计成预制的标准梁,跨度达70m的中等桥梁则经常使用节段式结构。捷克斯洛伐克在这两种装配式结构方面有着悠久的传统。近十年来,在这两种桥梁结构方面的重大革新正方兴未艾。其目的不仅为 Introduction The prefabricated prefabricated bridge structure occupies a significant proportion of the total bridge construction in Czechoslovakia. Bridges below 30m are often designed as prefabricated standard beams, while medium-span bridges spanning 70m are often of segmented construction. Czechoslovakia has a long tradition in these two types of fabricated structures. In the recent decade, major innovations in both types of bridge structures are in the ascendant.
