Abstract: Humber Bridge of England with its span length of 1,410m has been the world's longest span bridge. This paper concisely describes the design, construction and structure of this piece of gigantic architecture. Through a brief retrospect of the history of the steel suspension bridges, the author lays Special stress upon the principles and drawings of the problems of the cross-section forms, the wind load computation, the application of the wind channel, the nonlinear analysis and the load distribution, which appear in the design calculation with the purpose of explaining the experiences of the famous designer of large-scale steel suspension bridges-Freeman Fox Company which has emphasized the program design and the economic utility. The author also gives emphasis to the fact that among the large-scale bridges with the span length of over 1,000m. the steel suspension bridges are still uncomparable.

摘要： 跨径1410m的英国Humber桥,为迄今世界最大跨径的桥梁。本文扼要地叙述了此项工程的设计、施工和构造。通过钢吊桥发展历史的简要回顾,侧重介绍了大跨钢吊桥设计计算中诸如截面形式、风载计算、风洞实验的应用、非线性分析、荷载分配等问题的原理及图式;阐明以设计大型钢吊桥著名的Freeman Fox公司重视方案设计追求经济效益的经验。并强调对于跨径在千米以上的大型桥梁,钢吊桥仍然是无可比拟的。
