不同半径和缓和曲线的复曲线计算与敷设

摘要

在道路线路设计时,为适应特殊地形,常设置两个不同半径和不同缓和曲线同向相接的复曲线。对于复曲线的计算,相关文献都有各自的方法。根据对缓和曲线构成原理及选线测设的实践经验,提出一种复曲线的计算和敷设方法,较为简便、快捷。%In order to satisfy the special landform,complex curve with two different radius curves and transition curves connected in the same direction is commonly set up in road line design.For the calculation of complex curve,there are many methods in relevant literature.According to the composition principle of transition curve and practical experience in line laying,a calculation and laying method of complex curve is put forward,which is simple and convenient.
