Abstract: Alignment is the skeldton and outline, and its continuity, smoothness, flow ability and coordination are the key to interchange aesthetics.Interchange alignment is made up of horizontal alignment, vertical alignment and space alignment.According to the characteristics of interchange alignment aesthetics, this paper summarizes the content and demand of alignment aesthetics from horizontal, vertical, and space and sets forth the design method which can meet alignment aesthetics, in order to put forward good geometry alignment for traffic.

Key words: the characteristics of interchange, the aesthetics content and demand, the method of alignment design

摘要： 立交线形是构成互通式立交的骨架和灵魂,线形的连续性、顺适性、流畅性、协调性是构成立交美学的关键.立交线形主要由平面线形、纵面线形及平纵组合线形(空间线形)构成.本文结合互通式立立交线形的特点,从平面、纵面及空间三方面来阐述互通式立交线形美学的内容和要求,并提出满足线形美学要求的设计方法,目的是为立交行车提供优美的几何条件.
