南京长江二桥索梁锚固区模型试验分析

A Model Test on the Anchorage Zones of the Second Nanjing Changjiang River Bridge

南京长江二桥的索梁锚固形式采用锚箱式锚固结构 ,西南交通大学结构试验中心对其进行了静力模型试验研究。文中利用该试验数据 ,对锚箱式锚固结构中各板的应力分布及其连接可靠度等问题进行了分析研究 ,并与空间有限元模型分析结果相比较 ,得到了可靠的结论 ,为今后类似结构的设计提供参考。

A model test on the anchorage-box of the Second Nanjing Changjiang River Bridge was conducted at the Center of Structural Engineering Experiment of Southwest Jiaotong Universiy. The safety of and the detailed stress distribution in this structure, and the reliability of the connection between the anchorage-box and webs are investigated. The test results are practically in agreement with those of FEM calculation and are recommended as references for designs of similar structures.
