摘　　要：受通航、景观等因素影响,大跨径多跨连续梁桥在工程中应用越来越广泛。该桥桥型,除了具有大跨径少跨连续梁的一般受力特点以外,由于连续长度较长,具有伸缩量较大、合拢顺序多样等特点。论文以武荆高速汉江公路大桥主桥为例,分析研究大跨径多跨连续梁设计的技术要点。Considering the impact of navigation,landscape and other factors,the long and multi-span continuous girder bridges are applied more widely in the engineering projects.In addition to the general mechanical characteristics of the long-span continuous girder bridges,this brigde has the characteristics of more stretching and diverse closure sequences due to the long length.On the case of The Han River Bridge on the Wujing Highway,we analyzed and researched the technical points of long and multi-span continuous girder bridges as follows.
