摘　　要：结合京津客运专线简支箱梁的架设方案,介绍了该工程所采用的架梁设备和架设顺序等,并重点介绍了箱梁纵横向准确对位方法、千斤顶配合架桥机快速落梁和安装支座后压浆等关键施工技术,对同类工程有参考意义。With the erection plan for the simple-supported box girders of the Beijing-Tianjin Special Passenger Railway as a practical example, the paper outlines the erecting equipment and the erecting sequences adopted for the project, with stress placed on the key construction techniques such as the accurately longitudinally-transversely positioning methods of the box girder, the quick-lowering method of the box girder with jacks in support of the bridge erector, the slip casting of concrete posterior to the fixing of the support bearing, etc. The project may well serve as a reference for similar projects in future.
