摘　　要：移动支架造桥机曲线过孔技术,是铁路建设中曲线节点拼装的技术难题。以西平铁路南石窟寺特大桥的施工为依托,通过设置辅助过孔支墩,详细计算造桥机转向推力,过孔施工过程中进行全面监测,确保造桥机曲线过孔安全、快捷。Curve track punching technology of travelling trestle bridge fabrication machine is a technical problem of curve joint assembly in railway construction. Based on Southern Shikusi Bridge construction for Xi＇an to Pingliang railway,this paper calculates the steering thrust of bridge fabrication machine by setting the auxiliary piercing buttress,overall monitoring is implemented in curve track punching process,which ensures the safe and rapid curve track punching process.
