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.
