复合形曲线中、边桩坐标计算的统一模型

A Unified Model for Calculating Coordinate of Center and Side Pile in Compound Curve

根据回旋线特性,推导出回旋线上任意点的曲率圆心,得出在测量坐标系下任意段不完整回旋线向测量坐标系的转换公式,以及复合形曲线上任意点中、边桩坐标计算的统一公式,建立了复合形曲线上中、边桩坐标计算的统一模型。

By deducing the curvature circlecenter coordinate of spiral, the author introduced the formula for transforming local coordinate system to global coordinate system. And established a unified model for calculating coordinate of center and side pile in compound curve.
