METHOD FOR EVALUATING TRACK SUPPORT RIGIDITY
PROBLEM TO BE SOLVED: To provide a method for evaluating track support rigidity that allows the easy evaluation of the difference between a track support rigidity value for an actual track in operation and a track support rigidity value calculated using constants assumed by a design.SOLUTION: An amount of rail settlement for when a train passes over a rail of an actual track in operation is measured, and a monograph indicating a relation between an amount of rail settlement for each type of rolling stock on a line section and a track support rigidity value based on the theory of a girder on an elastic bed is obtained beforehand. A track support rigidity corresponding to the measured amount of rail settlement is then obtained based on the monograph.SELECTED DRAWING: Figure 3
【課題】実際の営業線における軌道支持剛性と、設計で想定した定数を用いて計算される軌道支持剛性との差異を簡易に評価することができる軌道支持剛性評価法を提供する。【解決手段】実際の営業線における列車通過時のレールの沈下量を測定し、弾性床上の梁の理論に基づいて、当該線区の車両種別ごとのレールの沈下量と軌道支持剛性との関係を示すモノグラフを、レール種別ごとに予め求め、前記モノグラフに基づいて、測定したレールの沈下量に対応する軌道支持剛性を求める。【選択図】図３
