摘　　要：利用桥梁—道碴—轨道的统一模型，对桥梁温度伸缩、桥梁挠曲作用以及制动力作用下的桥轨受力关系进行了分析。Relationship between forces born by bridge and rail under the action of temperature variation, deflection and braking are analysed by using brldge-ballast-rail as an unified model, and simply-supported bridges,30 m and 40 m in span length, are calculated with a programme of finite element of two-dimensional frame structure.

关 键 词：高速铁路简支梁桥 纵向力计算 温度伸缩 挠曲作用 制动力作用 受力关系
