屋代南、北桥计划的结构形式是梁的刚度较高的新型PC斜拉桥 ,具有经济性、挠度特性、施工性、景观性等优点 ,是 10 0m左右跨度的铁路桥很适合的桥式。桥梁设计时 ,矮塔斜拉桥作为第一座铁路桥 ,斜索拉力与过去的斜拉桥相同 ,取抗拉强度的 40 %。但该桥是采用新型结构的斜拉桥 ,
The structure of North South and North Bridge planned is a new type of PC cable-stayed bridge with high rigidity of beam. It has the advantages of economy, flexibility, construction and landscape. It is a very suitable bridge for railway bridges with a span of about 10m. The bridge design, the dwarf tower cable-stayed bridge as the first railway bridge, cable tension and past the same cable-stayed bridge, take the tensile strength of 40%. But the bridge is a new type of cable-stayed bridge,
