铁路中桩坐标统一计算模型

针对铁路提速及兴建客运专线后，铁路测设的实际需求，直接运用直线方位角和曲线特征计算铁路直线、缓和曲线和圆曲线的逐桩坐标以及曲线的主点里程和坐标，而不需要进行坐标转换，并对一些复杂线形中要用到的非完整、非对称缓和曲线上点的坐标进行了分析．此方法对公路的中桩坐标计算也可以应用．

The Unified Calculating Model of Middle Stake Coordinates in Railway

The azimuth of straight line and curve characteristic is used to calculate some coordinates of the straight line,the transition curve and the circular curve of the railway and to calculate mileages of the curve according to measuring and setting of the railway after speed increasing of the railway and constructing the passager dedicated railway.This method does not need to convert measurement and analyses some coordinates which are points on the non-holonomic and asymmetric transition curves.The calculating...
