摘　　要：随着城市互通立交形态多元化的演变,传统的立交形式已经不足以适应一些特殊的路网节点。一个立交中出现多个主线流向,使得公路主线分合流设计在城市道路设计中也开始得到应用。结合中环线浦东段申江路立交设计,对主线分合流设计在城市互通立交设计中所涉及的几个主要问题进行简要的分析与探讨。With the urban interchange transformed into multiple forms, the conventional form of interchange is no longer applicable to some special nodes in the road network, i.e. several main line traffic flows appear on one interchange, leading to the application to the urban road design of separate and combined main line flows, from which some key problems are discussed and analyzed in connection with the design of Shenjiang Rd. Interchange on the Mid Ring Rd (Pudong Section).
