摘 要: 當(dāng)定測中線遇到障礙時，在中線某一側(cè)設(shè)置加樁，即可有效地避開障礙物物而完成縱橫斷面的測量，該文給出了計算加樁點(diǎn)所在橫斷面的里程、加樁點(diǎn)距中線的平距及橫斷面方向的公式。

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
