摘　　要：根据有限位移理论中的虚功原理 ,推导了双薄壁墩 T构在横向风力作用下的静力稳定系数的表达式。算例分析表明 ,双薄壁墩 T构在施工中具有很好的静力抗风稳定性。The static wind stability factor of T-Frame Bridge with double slander piers is derived according to the Principle of Virtual Work in Finite Displacement Theory. By example analysis, the paper indicates that T-Frame Bridges with double slender piers have strong wind stability even if the pires are very high.
