摘　　要：铁路轨道测量仪是用于测量铁路轨道内部、外部几何参数的铁路专用计量器具。铁路轨道测量需与全站仪组合应用。为确保铁路轨道测量仪测得的线路横向偏差和垂向偏差示值误差准确、可靠,研制轨道测量仪线路横向偏差和垂向偏差示值误差校准装置,介绍校准操作步骤,并评定测量结果不确定度。评定结果表明:铁路轨道测量仪线路横向偏差和垂向偏差示值误差测量结果的扩展测量不确定度,均小于目标测量不确定度,校准装置能够用于测量铁路轨道测量仪线路横向偏差和垂向偏差示值误差。The measuring instrument for railway track is a railway specific measuring instrument used to measure the internal and external geometric parameters of railway track.The measuring instrument for railway track needs to be combined with the total station for application.To ensure the accuracy and reliability of the indication errors of the lateral and vertical deviations measured by the measuring instrument for railway track,a calibration device for the in⁃dication errors of the lateral and vertical deviations of the measuring instrument for railway track is developed.The calibration operation steps are introduced,and the uncertainty of the measurement results is evaluated.The results show that the extended measurement uncertainty of the indication errors of the measurement results for the lateral and vertical deviations of the railway line measured by measuring instrument for railway track is less than the target mea⁃surement uncertainty,and this calibration device can be used to measure the indication errors of the lateral and verti⁃cal deviations of the railway line measured by the measuring instrument for railway track.
