摘要
结合汀泗桥140 m钢箱系杆拱桥的施工监控实例,简要的介绍了高速铁路客运专线下钢箱系杆拱桥拼装与无砟轨道施工的变形控制,通过实测值与理论值的对比分析来指导施工,以期保证桥梁的实际受力符合设计受力状态,桥梁线型满足运营要求。
Combining the example of construction observation of 140 m steel box tied arch bridge of Tingsi, we simply introduce the deformation control of assemble of steel box tied arch bridge and construction of ballastless track about high-speed railway passenger line. Through the analy- sis and comparison between the measured value and theoretical value, the construction can be guided and the corresponding between bridge＇ s actual stress state and design stress state can be ensured so that the linearization of the bridge will meet operational requirement.
