| 摘 要： | 作为一种新型的减振轨道,梯形轨枕轨道已在国内的城市轨道交通中有所应用.该文介绍了在北京地铁五号线高架桥梯形轨枕轨道试验段进行的一系列现场试验,以及为验证其减振特性进行的室内试验.通过对轨道不平顺进行测量,并测试了当列车分别运行在梯形轨枕轨道和普通无碴板式轨道上时钢轨、轨枕和桥面的振动响应,该文对测试数据在时域和频域进行...

| Abstract: | Ladder track is a new type of vibration-reduction track system that has been applied to several urban railways in China.A series of experiments were carried out on the ladder track installed on the trial section of an elevated bridge on the Beijing Metro Line 5.The vibration transmission behaviours of the track were tested in the lab.The track irregularities were measured and the dynamic responses were measured of rails,sleepers and bridge deck when the train running on the ladder track and the common non-b... |
