摘　　要：对李子沟特大桥主体结构施工时的临时设施进行抗风设计 ,增强临时设施的抗风性能 ;并对施工阶段主体结构的典型工况进行动力特性分析 ,计算风载内力 ,提出各施工阶段相应的抗风安全措施。Wind resistance design was applied to the temporary structures of Lizigou Extra-large Bridge to increase its wind resistance. An analysis was made of dynamic property of main structure of the bridge under typical working conditions, and wind load internal force was calculated. Wind resistant measures were put forward at each construction stages.
