摘要
简要介绍了组合结构桥梁在欧美等发达国家的发展应用情况,接着对组合钢板梁桥、组合钢箱梁桥、波折腹板组合箱梁桥以及钢桁腹杆组合桥等城市高架桥梁中常用的组合结构桥梁的技术特点进行了分析与阐述,对近年来为提升组合结构桥梁在小跨度范围的竞争力而开发的新型组合结构桥梁的技术特点与创新点进行了介绍。最后指出:组合结构桥梁可以从钢桥与混凝土桥中找到共同结合点,使结构设计、施工、维修更趋合理并具有全寿命经济性。应该在新一轮城市桥梁建设中抓住机遇、大力发展。
The development of composite bridge in developed countries such as the countries in Europe and America etc.was intro- duced firstly.Then the technical characteristics of composite plate girder bridge,composite box girder bridge,composite bridge with corrugated steel webs,composite truss bridge were analyzed and expatiated.The technical characteristics and innovative points of new-style composite bridge,improved in recent years in the competitiveness of composite bridge in short-span bridges,were intro- duced.In the end,it concludes that the common points of steel bridges and concrete bridges can be found to make the design,con- struction and maintenance of composite bridges more reasonable and more economical in life-time circle,and the composite bridges should be developed strongly in the new circle of city bridge construction.
