悬索桥发展至今已有一百多年的历史，随着技术进步，悬索桥不论在跨径还是在技术上都有重大突破，审视当今各国悬索桥技术的新进步，使我们有条件采纳当今世界上最先进、最合理又适合我国国情的技术，对我国悬索桥技术的顺利发展将是很有益处的。文中仅对各国悬索桥的索塔架、主缆效率、主缆架设方法及结构构造上的若干进步等作以介绍。
With the progress of technology, the suspension bridge has made a great breakthrough both in terms of span and technology. Examining the new progress of suspension bridge technology in various countries nowadays makes us have the conditions to adopt the most advanced technology in the world , The most reasonable and suitable for China’s national conditions of technology, the smooth development of China’s suspension bridge technology will be very beneficial. The paper only introduces the cable tower, the efficiency of the main cable, the method of erecting the main cable and the several structural improvements of the suspension bridges of all countries.
