Factors Which Effect Track Alingnment Irregularity Detecting Precision

This paper advances the problem of track alingnment irregularity,presents the effect of track alingnment irregularity when the train runs faster, gives briefs on the several factors which effect detecting precision of the track alignment irregularity,and brings forward the reformative projects relative to factors.The factors include:Method of Chord Measuring that effects detecting precision of the track alignment irregularity,the error caused by using the arithmetic of “Using small fetch big”,the error brought about by measuring the mileage on one side.
