(同济大学建筑设计研究院，上海 200092)［摘要］南洲大桥为弯塔斜拉桥结构。该桥的斜拉索采用钢锚梁锚固系统。通过理论计算和模型试验结果验证索塔受力明确合理，在各种工况下受力均满足规范要求。［关键词］南洲大桥；弯塔斜拉桥；索塔锚固系统；受力分析
Design and Mechanic Analysis for Anchor System on Pylon of Guilin Nanzhou BridgeLi Xiaofeng，Chen Hefeng，Zheng Benhui(Architectural Design and Research Institute of Tongji University,Shanghai 200092,China)Abstract:The pylon of Guilin Nanzhou Bridge is curve,and the steel anchor beam system on pylon is complicated. According to the analysis of theoretical calculation and model experiment,the design of anchor system of pylon is proved safe and reliable,and meets with the criterion at the specified states.Keywords:Nanzhou Bridge；curved pylon cablestayed bridge；anchor system of pylon；mechanic analysis作者简介：励晓峰(1966-)，高级工程师，工学硕士。参考文献［1］公路桥涵钢结构及木结构设计规范(JTJ 025—86)［S］.
