非对称型缓和曲线的计算与测设

Calculation and Setting-out of Asymmetric Connecting Curve

在城市大型交通工程的线形设计中,为了适应变速车道的设计需要,必须采用非对称型缓和曲线。本文主要介绍非对称缓和曲线的计算公式与测设方法。

Asymmetric connecting curve must be used in alignment design of the large citied traffic engineering, for suiting the requirement of speed change lane design. This paper state that the calculation formula and the setting - out method of asymmetric connecting curve.
