摘要
本文介绍具有缓和曲线圆曲线的2种测设方法:a.分布测设缓和曲线和圆曲线;b.在直缓点或缓直点1次设站连续测设近端缓和曲线和圆曲线。同时给出2种测设方法的切线支距法和偏角法的公式。
This paper introduces two design and layout methods with transition circle curve, layout step by step and layout continuously. It also provides formula of the method of deflection angles and tangent offset of the two methods.
