Zusammenfassung: | The invention relates to a resonant anti-seismic ballastless track, which is used for effectively attenuating large-displacement vibration energy from seismic waves and reducing the damage of the seismic waves to a track structure. Comprising track plates which are continuously laid above a foundation in the line direction, transverse supporting blocks which protrude downwards are arranged on the longitudinal end portions of the bottom faces of the track plates, longitudinal supporting blocks which protrude downwards are arranged on the transverse end portions of the bottom faces of the track plates, and transverse grooves and longitudinal grooves which are used for the transverse supporting blocks and the longitudinal supporting blocks to be embedded are correspondingly formed in the top face of the foundation. Middle grooves are formed in the positions, corresponding to the centers of the track plates, of the top face of the foundation, spring vibrators are arranged in the middle grooves, and sliding vibrat |
