TRACK BED LATERAL RESISTANCE FORCE TEST DEVICE AND TRACK BED LATERAL RESISTANCE FORCE TEST METHOD
To provide a track bed lateral resistance force test device capable of measuring a track bed lateral resistance force reflecting the state of a lifted sleeper.SOLUTION: A track bed lateral resistance force test device 100 comprises: a sleeper lifting unit 110 for lifting a sleeper 20, from which a rail 10 and a rail fastening device 30 have been removed, by a prescribed amount from a track bed 50 in a state in which relative displacement is possible in the lateral direction of a track; a load unit 120 that inputs a force in the lateral direction of the track to the sleeper lifted by the sleeper lifting unit; and a displacement measurement unit 130 that measures the displacement of the sleeper in the lateral direction of the track.SELECTED DRAWING: Figure 2
