Abstract:When obstacles exist in the direction of the center-line, the longitudinal profile and cross-section survey can be made by setting up an additional peg on one side of the center line to avoid the obstacles. This paper gave out the corresponding equations for calculating the mileage of the cross-section in which the peg lies, the horizontal distance between the additional peg point and the center-line, and the direction of the cross-section.
Key words: easement curve mileage cross-section
