公路卵型曲线测设新方法研究

RESEARCHING A NEW LOFTING METHOD FOR GEE-TYPE CURVATURE OF HIGHWAY

卵型曲线是高等级公路设计中常用的一种线型 ,详细介绍了将卵型曲线分解成几个相邻的大圆曲线连接的基本平曲线 ,然后对基本平曲线进行测设的方法。这种方法较传统的卵型曲线的计算与测设更为简便 。

The Egg-type curvature is one of the commonly used lines in the high-level Highway. This paper introduces a new mathod, which divideds the egg-type curvature into circle-type curvatures before lofting. This method is more effective in computing and lofting.
