摘　　要：车速的逐步提升和旅客对乘坐舒适性的要求使得桥梁的设计思路已从过去的强度设计转化为刚度设计。对比分析了《城市轨道交通桥梁设计规范》和《新建时速200～250公里客运专线铁路设计暂行规定》中桥梁的适用条件和刚度标准,并简述了其对实际桥梁设计的影响。With the improvement of speed and the demands for passenger comfort,the design ideas of railway bridge have converted from strength design to stiffness design.The applicable condition and the rigidity standard of bridges in the Code for Urban Rail Transit Bridge Design and the Interim Provisions on the Design of Newly Built Passenger Dedicated Line with Speed of 200-250 km/h are comparatively analyzed,their effect on the actual bridge design is briefly studied.

关 键 词：城市轨道交通桥梁 铁路客运专线桥梁 设计刚度标准 舒适性 安全性 自振频率
