摘　　要：20世纪 80年代以来 ,日本、欧洲、中国 (包括香港 )等地区相继建成了许多大跨度悬索桥和斜拉桥。此外 ,以法国为代表的欧洲和日本对钢 -混凝土组合结构技术进行了深入的研究和广泛的应用 ,使钢桥技术有了飞跃的发展 ,钢桥不仅在大跨度领域占有绝对优势 ,在中小跨度领域也有很强的竞争力。在 2 1世纪 ,桥梁建设的主要任务是降低成本 ,缩短工期 ,延长使用寿命 ,满足环境保护的要求等等。本世纪初 ,将是中国桥梁建设持续发展的重要时期 ,因此 ,回顾钢桥的发展历史 ,积极吸取国外桥梁先进技术 ,总结我国近期桥梁建设的经验 ,并形成一个良好的桥梁技术发展环境 ,将是我们当前的主要课题。Since the 80 s, enormous large span suspension bridges and cable stayed bridges have been built up in Japan, Europe and China (including Hong Kong), Steel concrete composite structure has been intensively studied and is used in engineering projects of France, other European countries and Japan. All these activities resulted in considerable improvement of the welded steel bridge technology. Nowadays, steel bridge structure not only holds a dominant position in the large span bridge construction, but also shows its competiveness in building small and medium span bridges. In the 21st century, the bridge construction shall be carried out at reduced the cost, short construction period, long service life and up to environment protection standard. The early 21st century will see a key stage of continued development of the bridge construction in China. We need comprehensively review the steel bridge growth history, actively absorb the advanced techniques related in foreign countries, systematically summarize the experience of bridge construction recently undertaken in China and construct a good environment suitable for improving bridge technology.
