Abstract:

The coordinate calculation of the highway curves is divided into three basic types, i.e., straight section, circular curve and transition curve, on basis of the coordinate increment principle. Without coordinate transformation, the survey coordinates of the stakes on the alignment of the centerline and sideline are directly worked out, which simplifies the calculation principle and reduces the calculation quantity. Furthermore, coordinate calculation is made for project cases by using the strong calculation functions of Excel.
