| Abstract: | On the basis of GIS road line selection design system, a fast calculation method of coordinates of center and side-stakes on the road line--circle center moving method was presented. The least square method was used to fit the ground level line into a bidirectional lateral grade, and then to calculate the cross-sectional areas of earth work, effectively ensuring the calculation accuracy together with improving the calculation speed. |
