互通立交设计过程中,需要考虑平面上主交通流及各方向交通量分配情况;是否顺应地形,回避重要地物;纵面上各匝道与匝道、主线与匝道间的衔接是否顺畅;连接部高程数据的调整是否平顺等综合影响。互通立交中纵面灵活、巧妙的设计能够起到事半功倍的功效。 In the process of design of interchange, it is necessary to consider the traffic flow in the main plane and the distribution of traffic volume in all directions; whether it conforms to the terrain and avoid the important features; whether the connection between the ramp and the ramp, the main line and the ramp on the longitudinal surface is smooth; Data adjustment is smooth and other comprehensive impact. Interchanges in the vertical and flexible, clever design can play a multiplier effect.
