Research on Linear Fitting Method of Longitudinal Section of Old Airport Runway |
| |
| Abstract: | By studying the linear characteristics of the longitudinal section of the airport runway, the constraint relationship between the straight section and the arc section has been analyzed, and the calculation equation of the longitudinal section of the old runway has been established. Based on the principle of the least squares, a calculation program has been written to solve the optimal fitting profile of the longitudinal section of the old runway through multiple iterations. The engineering example shows that the method is fast in calculation speed and accurate in calculation result, which is suitable for longitudinal profile fitting of old roadway at variable slope points, and is in line with the requirements of engineering design. |
