摘要
介绍一种新的端部处理方式,采用锚固地梁与无缝伸缩缝相结合的措施来连接连续配筋混凝土路面和铁路通道。锚固地梁主要用来约束路面面层的膨胀位移,无缝伸缩缝既保证通道的自由变形又保证接缝处的行车平整。通过ABAQUS有限元程序分析了锚固地梁的应力和位移,结果表明:该连接方式具有较好的适用性。
A new type of end treatment is introduced in this paper. Anchor beam combined with seamless expansion joint （SEJ） is used to connect CRCP and railway tunnel. In this end treatment, anchor beam is mainly used to restrain CRCP displacement caused by the expansion of CRCP. SEJ can ensure the free deformation of railway tunnel and guarantee the flatness of pavement. The stress and displacement of anchor beam are analyzed using finite element program ABAQUS. The result shows that this new connection is better applicable.
