缓和曲线坐标计算新法

在近几年的公路建设中,各种复杂的缓和曲线越来越多,如:匝道、C型曲线、S型曲线等,传统的计算方法在处理这类曲线时非常繁琐,在实际应用中有相当的困难。通过研究,本文介绍一种新的计算方法,它与传统的计算方法相比,新方法主要优点有两个:一是可以从任意一点开始起算,具有很大的方便性;二是计算项数可以进行灵活扩充,使之满足要求的计算精度。新方法的这些优点使其能够轻松处理各种复杂的缓和曲线,对实际的计算工作有一定的指导意义。

New method of spiral curve coordinate calculation

On highway construction in last few years,many kinds of complicated spiral curve are used more commonly,such as ramp,C-type curve,S-type curve,etc.It's very complicated in processing these curves with traditional calculation method and hard to apply actually.Through research,a kind of new calculation method is found now.Compared with the traditional calculation method,it has two major advantages.Firstly,it can start counting at random point,which is very convenient.Secondly,its number of terms can be extended flexibly to meet the accuracy.These advantages of the new method make it handling many kinds of complicated spiral curve easily and have some guide significance in actual calculation.
