摘　　要：针对橡胶弹簧浮置板道床独特的结构,对橡胶弹簧浮置板道床区段和普通整体道床地段列车通过时的钢轨、道床、隧道壁的垂向振动加速度进行现场实测,通过测试数据分析得出了橡胶浮置板的振动特性及减振效果。期望研究结果对类似工程的减振型式选型、设计取值提供参考和借鉴。Aiming at the unique structure of rubber spring fl oating slab track,this paper discusses the fi eld actual measurement on vertical vibration acceleration of the rail,slab,tunnel wall in rubber spring floating slab track section and in the ordinary monolithic slabsection when trains pass through.Through the analysis of test data obtained,the effect of vibration features and damping of the rubber fl oating slab is given.It is hoped that the research results can provide references for the selection of the type of vibration control and the design value of similar projects.
