摘　　要：为了减少轨距尺超高测量装置中轴线与轨距尺尺身中轴线不平行引入的额外误差,根据JJG219—2015《标准轨距铁路轨距尺》检定规程规定,在轨距尺检定器上放置1对倾角垫块,测量轨距尺超高示值变化量,以确定轨距尺是否合格。针对倾角垫块等厚和不等厚2种情形,分析超高示值变化量的测量方法。以标尺类铁路轨距尺为例,说明超高示值变化量测量方法的应用。In order to reduce the extra error when the central axis of the super-elevation measuring device is not parallel to the central axis of the track gage,according to the regulation of JJG 219—2015 Track gages for standard gauges railway,it is necessary to place a pair of inclination cushion blocks on the verification device for the track gage to determine whether the the track gage is qualified when measuring the change of the super-elevation indication value of the track gage.Aiming at the two cases of equal and unequal thickness of inclination cushion block,the measurement method of change of super-elevation indication value is analyzed.Taking ruler type the track gage as an example,the application of measurement method of the change of the super-elevation indication value is explained.
