摘　　要：以川藏308国道通麦特大桥为背景,首先介绍该桥主梁风洞静力试验及其结果;其次研究主缆矢跨比、主缆边跨角度等因素对主梁横向静风位移的影响;最后比较分析本桥主缆空间特性对横向静风位移的影响。风洞试验和参数研究的结果,对同类桥梁的静力抗风性能设计提供一定的参考依据。Based on Tongmai Extra-Large Bridge of Sichuan-Xizang 308 National Highway,this paper first introduces the static test&results of the main girder of the bridge in wind tunnel,then studies the influence of the main cable rise span ratio,the main cable side span angle and other factors on the transverse static wind displacement of the main girder,and finally compares the influence of the spatial characteristics of the main cable on the transverse static wind displacement of the bridge.The results of wind tunnel test&parameter study provide some references for the static wind resistance design of similar bridges.
