对同一坐标系平曲线路基边线方程的分析

为解决平曲线路基边线测设过程中的精确放样问题,利用坐标系的旋转平移变换原理,分析了在同一直角坐标系中,求解第一缓和曲线、圆曲线和第二缓和曲线的中线和边线参数方程,并结合实例,对成果进行了验证。

Analysis the plane curve roadbed side equation in the same coordinate system

In order to resolve the precision lofting problems in the plane curve roadbed side design process,with the revolution and translation transformation principle of coordinate system,the solution of the central line and border line parameter equation of the first easement curve,circular curve and the second easement curve were analyzed in the same rectangular coordinate system.Combined with the example,the result was proved.
