摘要
介绍了圆曲线、缓和曲线的测设元素的基本概念,圆曲线、缓和曲线上各里程桩在切线直角坐标系和测量坐标系中的坐标计算公式,提出了利用全站仪对曲线上各里程桩进行极坐标测设的原理和方法。
Introduces some basic layout survey elements of circular curve and connecting curve dis-cusses some relative elements on main points,mile posts coordinate in the surveying system and or-thogonal system of those curves and suggest the use of electronic total station for polar coordinates survey of circular curve and connecting curves.
