摘　　要：为了对比地铁隧道内预制与现浇钢弹簧浮置板的减振性能,基于有限元法,建立地铁车辆-轨道-隧道-土体耦合动力学模型。利用该模型,对车辆通过普通整体道床、预制钢弹簧浮置板及现浇钢弹簧浮置板轨道的动力性能及减振效果进行对比。仿真分析可为地铁隧道内预制钢弹簧浮置板的应用和推广提供参考。In order to compare the vibration reduction performance of prefabricated and cast-in-place steel spring floating slab track in subway tunnel,the coupling dynamic model of metro vehicle-track-tunnel-soil was established based on finite element method.Using this model,the dynamic performance and damping effect of vehicles passing through common monolithic track bed,prefabricated steel spring floating slab track and cast-in-place steel spring floating slab track are compared.The simulation analysis can provide reference for the application and promotion of precast slab in subway tunnel.
