摘　　要：研究目的:针对高速铁路桥隧紧密相连路段,既有设备无法作业的施工难题,本文旨在设计一种集运架功能于一体,整机穿越隧道,能够实现紧邻隧道口和隧道内架梁作业的架桥机。研究结论:本文研究的SLJ 900/32流动式架桥机方案:(1)主支腿采用铰接三角形结构,上部安装支撑轮系,抵抗过孔产生的倾覆力矩,形成自稳定体系,无需采取锚固措施;(2)主支腿托轮系统采用恒定驱动技术,实现了不同类型驱动的同步控制,提高了设备的安全可靠性;(3)通过主辅支腿功能转换技术,实现了无导梁支持的架梁模式,简化了作业流程,实现了首末跨、隧道进出口和隧道内架梁的功能;(4)主支腿安装自动预警安全装置,作业时能够实时反映主支腿工作状态,具有预警和停机保护功能;(5)该研究成果可应用于高速铁路普通工况及桥隧紧密相连路段特殊工况的大吨位箱梁运架施工。Research purposes： In order to resolve the problem that the box girder is difficult to be transported and erected by the existing transportation ＆ erection equipment in the bridge -tunnel immediately joint section on high - speed railway, this paper studies the design of bridge erecting machine with transporting and erecting and meeting the whole machine crossing tunnel, erecting box girder at tunnel entrance and erecting box girder inside tunnel. Research conclusions： The scheme of the SLJ 900/32 mobile bridge erecting machine in this paper is as follows： （ 1 ） The main support leg adopts the joint - dominated triangular structure. The used on the main support leg. Without any anchor measures, the main support leg is supporting wheel train mechanism is designed to realize the structure self- stabilization and can resist overturning moment which bridge erecting machine over the span to the next pier. （2） With the constant drive mode on the main support leg, the bridge erecting machine realizes the synchronization control mode of different driving method and improves the safety and reliability in operation. （3）Through alternating functional transformation technique of the main support leg and auxiliary support leg, the bridge erecting machine can over the span to the next pier without the need of the guide beam. The operational process is simplified and the bridge erecting machine can erect box girder at tunnel entrance and erect box girder inside tunnel. （4） This application verifies that the main support leg with the automatic warning detecting device can achieve not only the real time and on -line monitoringinternal force, but also the automatic warning even emergency stop protection when the internal force exceeded to ensure safety in operation. （5） This research results are available for transporting and erecting large - tonnage concrete box girder in normal working conditions and in the bridge - tunnel immediately joint section on high - speed railway.
