摘要
以陇西互通立交为例，通过对立交周围路网交通量和通行能力的分析，对确定该立交应具有二条定向匝道的两方案进行论证，根据对两个方案的造价分析以及立交内排水可行性等综合考虑，选择出合理、经济、美观的方案，文中还阐述了集散道的功能。
Taking Longxi Interchange for example ,this article discusses the two precepts in which the interchange should have two directional ramps by analyzing the traffic volume of the highway net around the interchange and the traffic capacity And through the analysis of the cost of the two precepts and overall consideration of drainability in the interchange, a reasonable economical beautiful precept has been selected.This article also expounds the functions of the collectordistributor road.
