WEAR DETERMINATION METHOD OF TRACK BALLAST AND WEAR DETERMINATION DEVICE
PROBLEM TO BE SOLVED: To provide a wear determination method of a track ballast which can exactly detect a state of a ballast which forms a ballast track of a railway, and thereby can easily perform the maintenance management of a railway track, and a wear determination device.SOLUTION: A wear determination method of a track ballast comprises: a striking process for imparting a strike to a ballast 2; a vibration detection process for detecting vibration which propagates the ballast 2 by the strike which is imparted at the striking process; and a deterioration analysis and determination process for analyzing a frequency characteristic of the vibration which is detected at the vibration detection process, and estimating a degree of the wear of the ballast 2 by comparing the analyzed frequency characteristic with a reference value.
【課題】この発明は、鉄道のバラスト軌道を形成しているバラストの状態を正確に検出することができ、これによって鉄道軌道の維持管理を容易に行うことができる、軌道バラストの摩耗判定方法及び摩耗判定装置を提供する。【解決手段】バラスト２に打撃を与える打撃過程と、該打撃過程で与えられた打撃によりバラスト２を伝播した振動を検出する振動検出過程と、該振動検出過程で検出された振動の周波数特性を分析するとともに、分析した周波数特性を基準値と比較してバラスト２の摩耗の程度を推定する劣化分析及び判定過程と、を有することを特徴とする。【選択図】図１
