刚性索悬索桥研究

Research of rigid cable suspension bridge

刚性索悬索桥是指主缆及吊杆为刚度较大的构件组成的悬索桥 .它解决了中小跨度时常规悬索桥刚度差、吊杆易疲劳等问题 .文中介绍了刚性索悬索桥的计算分析、构造措施和施工方法 ,给出了工程实例———于 1999年12月建成通车的江苏常州广化桥 ,说明刚性索悬索桥是一种很有应用前景的桥型 .

Rigid cable suspension bridge,whose main cable and hanger are rigid,can solve some problems of normal suspension bridge such as fatigue of hanger and lower rigidity of the structure.The analysis,design and construction of rigid cable suspension bridge are discussed in this paper,and a practice of this type of bridge—The Guanghua Bridge in Changzhou,Jiangsu province are given in the paper.
