The invention relates to the field of rail-flaw detection, particularly to a rail-flaw analyzing method and a rail-flaw detecting car. The rail-flaw analyzing method comprises the following steps: acquiring rail-flaw data; performing historical-flaw-data contrastive analysis on the acquired rail-flaw data so as to judge a rail-flaw developing trend; and performing at least four of the following analyses on the acquired rail-flaw data: circuit technique status analysis, rail tour-inspection analysis, rail corrugation analysis, rail fracture-surface wearing analysis, rail geometrical analysis, and roadbed and ballast bed analysis. According to the rail-flaw analyzing method disclosed by the invention, through comprehensive analysis for a rail flaw, the serious degree of the suspected flaw and a flaw developing speed can be judged, and a flaw grade is judged, so that setting a priority order during re-detection of a manual flaw detector is facilitated; reasons for generating flaws can be deeply analyzed, so that deep factors for generating the flaws can be eliminated in time, and the continuous generation of the flaws can be avoided.
