坐标法在双线铁路桥梁曲线布置中的应用

The Application of coordinate Method in the Curre Layout of Double-line Railway Bridge

本文以缓和曲线的参数方程为出发点，运用坐标转换原理，解决了不规则情况下双线铁路线间距计算问题，为双线铁路桥梁曲线布置提供了方便．

Based on the parametre equation of relaxed curve,this papper solves the distance computation problem between lines of double-line railway under irregular conditions by adopting the coordinate transformation principle. It provides convenience for the layout of double-line railway bridge.
