世界闻名的土木工程师林同炎教授,于1993年9月访华,来京进行学术活动,带来一篇刊载于《旧金山纪事》的文章,介绍了他在直布罗陀海峡修建4.9公里超长梁跨的设计方案。这一创造性的方案,获得国际桥梁与结构工程协会的优秀论文奖。今结合有关资料,对此文加以编译,尽快地献给读者。 跨海大桥以大跨度为宜,跨度超过1公里的大桥,桥式非悬索桥莫属。目前世界上已建成的悬索桥,最大跨度是英国的恒伯尔桥,跨度为1440米;正在修建的则是日本的明石海峡大桥,跨度为1990米。但跨度不可任意延长,国内外桥梁界不少专家,根据当代的技术及工业 World-renowned civil engineer Lin Tongyan visited China in September 1993 to conduct academic activities in Beijing and brought an article published in the “San Francisco Chronicle,” introducing his design of a 4.9-km long beam span in the Strait of Gibraltar. Program. This creative program won the Outstanding Paper Award from the International Association of Bridge and Structural Engineering. Now with the relevant information, to compile this article, as soon as possible to the readers. Bridge with a large span is appropriate, span more than 1 km of the bridge, bridge non-suspension bridge none other than. Currently, the suspension bridge built in the world has the largest span of Hangbol Bridge in the UK with a span of 1,440 meters. The Akashi Kaikyo Bridge under construction in Japan is spanning 1,990 meters. But the span can not be arbitrarily extended, many experts at home and abroad bridge industry, according to contemporary technology and industry
