摘　　要：系统回顾移动支架造桥技术在国内的进展情况 ,按PC箱梁在移动支架的位置 ,对现有的造桥机进行分类 ,对其 2种施工方式节段拼装法和整孔现浇法进行比较 ,并对造桥机的移动方式、造桥机对曲线PC桥梁的适应能力以及墩旁托架进行探讨和分析。The development of travelling trestle bridge fabrication machine in China was reviewed. Bridge fabrication machines were classified according to PC box girder's position in travelling trestle. A comparison was made between two construction methods: precast girder assembly method and cast\|in\|situ method. Explorations and analysis were also made of travelling mode of bridge fabrication machine, adaptability of the machine to curved PC bridges, and bracket around pier.
