The invention discloses a vibration reduction type uplift pile for a subway station. The vibration reduction type uplift pile comprises a pile body, a vibration isolation pile head fixed to the top of the pile body, a pile body stress main rib used for connecting the pile body and the vibration isolation pile head, and a prefabricated pile cap fixed to the vibration isolation pile head. According to the vibration reduction type uplift pile for the metro station, the anti-floating design requirement of the uplift pile is met, meanwhile, the vibration reduction effect of the uplift pile is achieved by designing a rigid-elastic-rigid transition type pile structure, when vibration generated by metro train operation passes through the uplift pile, vibration energy is weakened by a vibration isolation pile head in the uplift pile, and the anti-floating design requirement of the uplift pile is met. Therefore, vibration energy propagating outwards is greatly reduced.
本发明公开了一种地铁车站用减振型抗拔桩，包括桩身，固定在桩身顶部的隔振桩头，用于连接桩身及隔振桩头的桩身受力主筋，固定在隔振桩头上的预制桩帽；本发明公开的一种地铁车站用减振型抗拔桩，在保证抗拔桩抗浮设计要求的同时，通过设计刚‑弹‑刚性过渡型桩结构，从而实现抗拔桩的减振效果，当地铁列车运行产生的振动通过抗拔桩时，由于抗拔桩内的隔振桩头削弱了振动能量，从而大幅度的减少了向外传播的振动能量。
