Abstract: Steel spring floating slab tracks are equipped to reduce the vibration impact on precision instruments along the metro
lines, but the ground vibration would be amplified at the natural frequency of the tracks. In order to address the negative impact of
natural frequency vibration amplification on the surrounding environment of floating slab track, a full frequency control method con‑
sidering frequency matching for environmental vibration in collaboration with metro vibration sources and propagation paths is pro‑
posed, which is based on the theory of periodic structure bandgap structure. The effectiveness of this method is analyzed by estab‑
lishing a three-dimensional metro train-floating slab track coupling model and a finite element analysis model of track bed-tunnel-
soil-row piles. The research results show that the ground vibration can be reduced about 4~7 dB at the natural frequency of the
floating slab track plate by adjusting the band gap range of periodic pile to 7~9 Hz, eliminating the adverse effect of vibration ampli‑
fication at the natural frequency of the track. Compared to ordinary tracks, the environmental vibration comprehensive control meth‑
od proposed in this article has good vibration control effects and can effectively reduce the vibration level of sensitive points on the
ground in the full frequency range.
