| Abstract: | Bao-Xi Railway Ganquanluohe Large Bridge is a 6-single-line large bridge spanning Luohe River. It is designed to adopt the construction technique of segmental assembling with mobile bracket bridging machine from the sixth hole to the 11 th hole. In practice, the technique of integrated transverse movement of segmental assembly is used on Line-Two falsework. Some aspects of this technique such as construction scheme comparison, falsework layout, assembling, transverse moving methods as well as technical procedures are analyzed and addressed in this article. |
