Long-line engineering mileage pile integrated measuring and setting method adaptive to path change

The invention discloses a long-line engineering mileage pile integrated measuring and setting method adaptive to path change, and relates to a mileage pile measuring and setting method, which comprises the following steps of step 1, calculating the coordinates of a mileage point center line; during reckoning, distinguishing two conditions of a whole mileage point in a straight line segment and a curved line segment; 2, calculating the azimuth angle of the vertical line or the normal line of the central line, firstly introducing the azimuth angle of the vertical line or the normal line when calculating the coordinate of the mileage pile burying point; step 3, determining the distance between the burying point and the central line, determining the distance from each planned burying point tothe central line along the vertical line or the normal line; and step 4, calculating coordinates of the mileage pile burying point, finally calculating the coordinates of the mileage pile burying point by using the coordinate
