无碴型预制混凝土纵梁支承轨道减振性能的研究

Study of Damping Performance of Ballastless Track with Pre-fabricated Concrete Longitudinal Beams

通过落锤冲击试验,研究无碴型预制混凝土纵梁支承轨道的减振性能,并和其它减振轨道结构进行对比分析,结果表明该结构具有较好的减振性能,在城市轨道交通中具有良好的发展前景。

Through drop hammer impact testing, the low-vibration perfor-mance of the longitudinal beam-supported ballastless track isevaluated. Results from the analyses indicate that this type of trackhas better vibration reduction performance, which has a good pros-pect in urban rail transit.
