圆曲线中点设站放样方法讨论

Sampling method of station at points of round curve

结合实际经验,介绍了另一种较为简便的圆曲线放样方法——曲中设站放样法,就此法的运用进行了讨论,在此基础上,详细介绍并导出了另一种放样方法——对称式弦线支距法及其坐标计算式。

Combined with actual working experience, it introduces a simple sampling method of round curve,discusses usage of this method, and introduces & deduces another sampling method——symmetric string distance method & its coordinate calculative formula.
