摘要
研究目的:和公路桥梁相对而言,铁路桥梁荷载大,冲击力大,要求能抵抗自然灾害的标准高,特别是结构要求有一定的竖向横向刚度和动力性能。本文以大量事实论述了100多年来中国铁路建桥技术取得的举世瞩目的进步。研究结论:中国铁路桥梁研究制造出高强度耐久的新材料,设计出先进合理的桥式结构,拥有科学先进的制造和施工工艺设备。中国桥梁的设计和施工已经达到了世界先进水平。新世纪还需进一步开展多项科技研究。
Research purposes： Compared with highway bridge, railway bridge bears larger load and larger force of impact, so it requires higher standard for resistance to natural disaster, especially it requires certain vertical and lateral rigidity to its structure. The great achievements made in technology for construction of railway bridge in China over 100 years are expressed.
Research conclusions： China has researched and manufactured new durable materials for railway bridge, designed advanced and reasonable structures of railway bridge, and has advanced manufacturing and construction techniques and equipments. However, it is necessary for China to make further scientific and technical research on some fields of it.
