摘要
根据平行索面斜拉桥的结构特点,椒江特大桥主桥采用了一种组拼式索梁锚固构造。通过建立斜拉桥索梁锚固区的实体有限元模型,对组拼式索梁锚固区进行有限元分析,得出索梁锚固区的应力分布特征。计算结果表明,该结构设计合理可行,可为索梁锚固设计提供借鉴。
According to the structural characteristics of the parallel cable-stayed bridge,a kind of assembled structure of cable-beam anchorage zones is chosen for main bridge of Jiaojiang Bridge.A solid finite dement model of cable-beam anchorage zone of cable-stayed bridge is established,and the stress distribution characteristics of assembled cable-beam anchorage zone is obtained through the finite element analysis.The calculation results show that the structure is reasonable and it could provide reference for design of cable-beam anchorage zones.
