<p>The present invention discloses an apparatus for measuring a rail traveling direction displacement including a pair of rail fixing members (100) that are fixed while surrounding a lower portion of a rail (10) on one side, have hinge coupling portions (101), and are disposed apart from each other; a sensor casing (200) with both respective ends hinge-coupled with the hinge coupling portions (101) of the pair of rail fixing members (100) for hinge driving corresponding to sinking of the rail (10) on the one side; and an angle sensor that is disposed in the sensor casing (200) so as to measure an angular change of the pair of rail fixing members (100). The present invention can be applied even to concrete sleeper structures, provides high data reliability based on direct rail displacement measurement, and allows damage-free and stable measurement.</p> |
