为探明超大跨悬索桥在施工过程中的静风稳定性，采用三维非线性分析方法，对主跨3 500 m的超大跨CFRP(carbon fibre reinforced plastic)主缆悬索桥进行了施工阶段的静风稳定性分析，研究了3种交叉吊索对施工阶段静风性能和变形形态的影响.研究结果表明:随着加劲梁吊装逐步完成，结构静风稳定性不断降低，加劲梁合龙但尚未刚接阶段的静风稳定性最差;仅安装水平交叉吊索作用不大，竖向交叉吊索和综合交叉吊索可显著提高施工阶段的静风稳定性;加劲梁吊装完成率位于9. 8%一60.6%时，安装综合交叉吊索可取得较好的抗风效果，其余施工阶段可只安装竖向交叉吊索.
In order to verify the stability of the static wind of the super-long span suspension bridge during the construction process, a three-dimensional non-linear analysis method was used to conduct the static wind stabilization of the main cable suspension bridge with a span of 3 500 m and the carbon fiber reinforced plastic (CFRP) The results show that with the gradual completion of stiffened girder hoisting, the stability of the structure’s static wind decreases continuously, while the stiffener joins but has not been connected just before the stage Of the static stability of the worst wind; only horizontal cross-slings installed little effect, vertical cross-slings and cross-slings can significantly improve the stability of the construction phase of the static wind; stiffened beam lifting completion rate of 9.8% 60.6%, the installation of comprehensive cross-slings for better wind resistance, the rest of the construction phase can be installed only vertical cross-sling.
