Precision measurement control method of metro track structure construction

The invention specifically relates to a precision measurement control method of a metro track structure construction, which solves the problems of poor safety, smoothness and comfort of a line and high equipment abrasion and noise vibration in the operation process because the existing measurement control method of the track structure construction has multiple steps and the control benchmarks for measurement can not be reused. According to the precision measurement control method, precision measurement control is performed on the track structure by utilizing a method of establishing a track basic control network in combination with a total station and a track geometrical state measurement instrument, thereby realizing high-precision adjustment on the track; and the track geometrical state measurement instrument is applied so that the precision requirements on points in the metro track measurement are improved to be requirements on the overall smoothness of the line, thereby guaranteeing that the indexes of track gauge, high-low rate of change, track orientation, high and low smoothness and the like of the track are capable of meeting higher requirements; and besides, digitization and automation are realized.
