直线中线上自由站测设圆曲线

The Method of Setting Out the Circular Curves on free Station With Straight Center Line

本文介绍圆曲线的“一步测设法”,即在直线中线任意点同时测设国曲线的中线、内外边开挖线。实践证明该方法具有计算简单,操作方便,放样精度高,测设速度快,不受地形影响等优点.

The method of setting out circular curve in one station was discussed in this paper. This method layout the center line and two side lines of the circular curve in one station, which is simple in calculation, convenient in operation , precise in layout of location and free station.
