120km/h市域铁路桥上高等减振方案及减振预测
|
摘要
市域铁路的发展是城镇化的选择,以核心城市为中心加快市域铁路发展,可优化城镇空间布局,缓解城市交通压力。通过对国铁、地铁轨道减振方案的了解,参考双块式无砟轨道结构,总结出市域铁路无砟轨道高等减振结构,并对其安全性、平稳性指标进行评价,通过减振型轨道与非减振轨道振动计权加速度振级的差值进行对比,预测减振效果。
The development of suburban railway is the choice of urbanization. Taking core cities as the center to accelerate the development of urban railways can optimize the spatial layout of cities and relieve the pressure of urban traffic. Through the understanding of the national railway and subway track vibration reduction schemes, referring to the double-block ballastless track structure, the high-level vibration-damping structure of the ballastless track of the city railway is summarized, and the safety and stability indicators are evaluated. Finally, predict the vibration reduction effect by comparing the vibrational acceleration amplitude difference between the damping track and the non-damped track.
