斜拉桥作为一种新型桥梁,在当今世界得以快速建设和发展,而经轻盈优美的身影也屡屡登上方寸邮票。斜拉桥也称斜张桥,是将桥面用许多拉索直接拉在桥塔上的一种桥梁,由桥塔、拉索和梁体组成,是大跨度桥梁的最主要桥型。从墨西哥的这枚邮票中,我们可以清楚地看到由这3个部分组成的斜拉桥直观图(图1)。斜拉桥轻巧简洁,结构新颖,其优点是刚性大,抗风稳定性好,抗扭曲震动性能力强,充分展现出新时代的技术特征,给人以强烈的视觉上的震撼感。
Cable-stayed bridge as a new type of bridge, in today’s world to rapid construction and development, and the figure of light and beautiful have often boarded the inch stamps. Cable-stayed bridge, also known as diagonal tension bridge, is a kind of bridge that is used to pull the bridge deck directly with many cables. It is composed of bridge tower, cable and beam. It is the most important bridge type of long-span bridge. From this Mexican stamp, we can clearly see the visual representation of the cable-stayed bridge consisting of these three parts (Figure 1). The cable-stayed bridge is compact, compact and novel in structure. The advantages of the cable-stayed bridge are high rigidity, good stability against wind wind, strong resistance to twisting vibration, fully demonstrating the technical characteristics of a new era and giving a strong visual sense of shock.
