Description

本発明は、高温時における地震および地震後におけるレール温度の運転規制基準値の変更方法ならびにその変更システムに関するものである。   The present invention relates to a method for changing an operation regulation standard value of an earthquake at a high temperature and a rail temperature after the earthquake and a system for changing the same.

鉄道において、従来、高温時にはレールが伸びることによる座屈変形（張り出し）が懸念されるため停止や徐行の運転規制が行われる。また、地震時においても規定値以上の揺れが計測された場合には停止や徐行の運転規制が行われる。高温時にはレールが伸びることにより軸力が増大する。この際に地震動が作用すると弱い揺れでもレールに座屈変形が生じる可能性が増大する。また、強い地震動が作用した後にはレールの軸力状態が変化すると考えられる。この際、高温であれば通常は座屈変形しない温度でも、レールが座屈変形する可能性が高まる。   Conventionally, in railways, there is a concern about buckling deformation (overhang) due to the extension of the rail at high temperatures, so that stop and slow driving are regulated. In addition, stoppage and slowing-down operation regulation is performed when a vibration exceeding a specified value is measured even during an earthquake. The axial force increases due to the extension of the rail at high temperatures. In this case, if the earthquake motion acts, the possibility of buckling deformation in the rail increases even with a weak shaking. Moreover, it is considered that the axial force state of the rail changes after strong earthquake motion is applied. At this time, if the temperature is high, there is an increased possibility that the rail will buckle and deform even at a temperature that does not normally buckle and deform.
