The invention discloses an anti-settling subway rail, and belongs to the technical field of underground rail traffic. The subway rail comprises a rail support plate and rails which are parallelly arranged on the rail support plate at intervals, elastic support blocks are arranged between the rail support plate and the ground for supporting, a plurality of groups of damping devices are further arranged at the bottom of the rail support plate, each group of damping devices are symmetrically distributed on the two sides of each rail; and each damping device comprises an outer cylinder and an inner cylinder, the inner cylinder is fixedly arranged in the outer cylinder, a thin-wall cavity is formed between the inner cylinder and the inner wall of the outer cylinder, and a magnetic field generating device used for adjusting damping force is further arranged in the inner cylinder. According to the device, vibration reduction can be conducted on a moving subway train, and tunnel settlement caused by long-term circulation of subway vibration loads is prevented.
本发明公开了一种防沉降的地铁轨道，属于地下轨道交通技术领域，包括轨道支撑板、平行间隔设置在所述轨道支撑板上的铁轨，所述轨道支撑板与地面之间通过弹性支撑块支撑，所述轨道支撑板的底部还设置有若干组减震装置，每一组减震装置对称分布在所述铁轨的两侧；所述减震装置包括外筒体和内筒体，所述内筒体固定设置于外筒体内并与外筒体的内壁之间形成薄壁腔，所述内筒体内还设置有用于调节阻尼力大小的磁场发生装置。本发明装置可以对行进的地铁列车进行减振，防止地铁振动荷载的长期循环导致隧道沉降。
