초록

The track performance evaluation in curves of conventional line subjected to loading condition caused by tilting trains was carried out. And the correlations between train speed and track alignment was reviewed. The parameters of track alignment were determined by field investigation of all curves in conventional line. It was founded that the pressure of the rail did exceed the allowable stress when the tilting train speed was over 96km/hr in radius of 300m. As the radius of curvature is smaller, applied force on the track becomes larger in the curved track without regard to laying of the continuos welded rail. On the while, the change of applied force on the track corresponding to the change of the cant is not so large.
