城市轨道高架桥的选型及稳定性讨论

摘要

This paper mainly focus on how to solve the problem in the des igning o f track transportation high bridge, such as how to choose the proper style of gi rder and buttresses, how to control the perpendicular displacement and how to mi nish the longitudinal force etc. It also provides some useful suggestions for fu rther investigations.`%通过对几种城市轨道交通高架桥结构型式的分析比较，提出了选型 意见。针对高架 桥的稳定性，从施工和设计两方面提出了高架桥竖向变位控制措施，同时分析了高架桥纵向 力产生的原因，提出了高架桥设计中纵向力的处理方法。
