任意点设站测设同心曲线

On Random Station to Set out Stakes of Concentric Curves

分析了同心曲线的性质 ,提出了可在任意点设站测设同心曲线的原理及放样同心曲线的中线、侧线各桩并闭合于各自主点的方法 .

The paper analyzed the properties of concentric curve,the principle and method of setting out stakes of middle*.line & sidings on one random station and closed with main points.
