摘要
在给出线路任意点方位角概括模型的前提下 ,推导出适用于各种曲线元的中边桩坐标计算的通用公式 ;用实例验证了 4节点Gauss Legendre求积公式能确保计算精度优于 1mm。给出的用于编程的计算流程可解决实际工作中各种曲线坐标计算问题 。
In condition of having universal model for computing azimuth angle for random point in highway, this paper derives the general calculating formulae of coordinates of center and side stakes, which are applicable to all kinds of elements curves. It is proved that the calculating error of 4 node Gauss Legendre formulae is less than 1mm. The flow charts given herein can solve the coordinate calculating problems for all sorts of curves.
