Evaluation of Train Running Stability on Slab Track with Vibration Exciter

Cyclic load by train causes subsidence of railway level in tunnels, which is due to ground deformation under roadbed concrete. In consideration of progress of track disorder and core drilling results, the deformation of the roadbed concrete have been evaluated, but there have been no quantitative inspection method until the present. In this study, to develop a method for quantitative evaluation of train running stability on the slab track, a method to survey roadbed concrete by vibrating with small-sized and medium-sized vibration exciter was proposed. Vibration characteristic of roadbed concrete with accelerometers fixed around the vibration location was also evaluated. Then the correlation with progress of track disorder considered to be correlated with the soundness of roadbed concrete and the results of vibration tests was verified, and a method for evaluation with the correlation was proposed.
