The invention discloses a track fastening structure for subway vibration reduction. The track fastening structure comprises a base, support bodies and tracks; the bottom of the base is connected with the support bodies, and the tracks are arranged above the base; the two tracks are arranged in parallel, two sets of support bodies are arranged below the base, and a buffering piece is arranged between the two sets of support bodies and used for reducing vibration of the base in the horizontal direction. Each support body comprises a first elastic body, a second elastic body and a third elastic body; the upper portion of the first elastic body is connected with the base, the bottom of the first elastic body is connected with an upper supporting plate, the second elastic body and the third elastic body are symmetrically arranged at the bottom of the upper supporting plate in an inclined mode, and a lower supporting plate is arranged below the second elastic body and the third elastic body. The support bodies are arranged at the bottoms of the track roadbed, so that the horizontal or vertical amplitude of vibration of a subway on the track during running is reduced, the transverse and vertical natural vibration periods of the tracks are kept away from the outstanding period of vibration waves, and therefore, a vibration reduction effect is effectively improved.
本发明公开了一种地铁减振用轨道紧固结构；包括，基座、支座体、轨道；所述基座底部与所述支座体连接，基座的上方设置有轨道；轨道平行的设有两条，所述基座的下方设有两组支座体，两组所述支座体之间设有缓冲件，所述缓冲件减小基座的水平方向振动；所述支座体包括第一弹性体、第二弹性体、第三弹性体；所述第一弹性体上方与所述基座连接，第一弹性体的底部连接有上支板，所述上支板的底部倾斜对称设有第二弹性体和第三弹性体，所述第二弹性体和第三弹性体的下方设有下支板；通过在轨道路基的底部设置支座体，减小地铁运行中自身的振动对轨道水平或者竖直的振幅，使轨道的横向、竖向自振周期避开振动波的卓越周期，从而有效地提高减振效果。
