| Abstract: | The setting out of centerline pegs and side pegs of route constitutes most of the routine surveying tasks,and plays a very important role in the route construction.The computation of plane coordinates of centerline and its sideline is the key to the job of setting out with modern surveying instruments.Based on the fact that curvature of any point on a curve line varies proportionally with its curve length for all types of curve elements,it proposes a set of formulae which are versatile for the plane coordinates computation in the setting out of routes,including the azimuth formula,the formulae in numerical form for the coordinates of centerline and side pegs.Also,with the proposed universal formulae,the computations for the corresponding center pegs of a point off the centerline and the intersection problem of a straight line and the centerline are discussed,and then the solution schemes are given respectively. |
| Keywords: | setting out of plane route coordinates of centerline and side pegs |
