摘要
通过参加上海地铁二号线东西延伸段、莘闵轻轨交通线、西安地铁等工程的高架桥设计，经与铁路桥 和公路桥的比较，探讨了城市轨道交通高架桥设计上应考虑两个特殊问题：纵向力和竖向变位，并给出了设计 上的对策。
Through taking part in design of viaducts for the east and west extended sections of the Shanghai No. 2 metro line, the Xin-Min light-rail transportion line and the Xi'an metro project, etc, and by comparing with the railway bridges and highway bridges, there are two special problems that should be considered in design of viaducts for urban rail transit: i. e. the longitudinal force and the vertical displacement. The longitudinal force and the vertical displacement are explored in detail, and their corresponding countermeasures on design are proposed.
