在互通立交设计过程中,需要进行大量的匝道鼻端高程、纵坡计算,尤其是枢纽互通立交计算量非常大。一般来说,匝道鼻端高程的计算较为简单,而匝道鼻端纵坡的计算较为复杂,主要探讨匝道鼻端纵坡的计算方法。＂5m纵坡推算法＂计算较为繁琐,提出＂瞬时纵坡计算法＂,并通过实例与传统方法进行对照,旨在使鼻端纵坡的计算过程更简易。

In the process of interchange designing,it needs a lot of nose height and nose longitudinal gradient calculation,especially hinge interchange.Generally,the calculation of nose height is simple,but the calculation of nose longitudinal gradient is more complex,so this paper mainly discusses the calculation method of nose longitudinal gradient.＂5 m longitudinal gradient calculation method＂ is very cumbersome,this paper will put forward a new method of ＂instantaneous nose longitudinal gradient calculation method＂,and through example,comparing with the traditional method,in order to make it easier to calculate the interchange nose longitudinal gradient.
