摘要
介绍了城市道路平面交叉口的各种型式及其特定的适用性 ;着重介绍了拓宽的方法和渠化的主要作用 ;分析了拓宽和渠化后的各种交叉类型的一般应用和功能特征 .通过分析可知 ,每种交叉类型不论在形状和渠化程度上都有很大差别 ,但介绍的各种交叉类型足以包括平面交叉设计的一般应用 .
The artical introduces some kinds of model and special adaption in plane intersection design of city road ,Especially the way of expansion and the main affect of irrigation. It analyses the normal function and feature of the intersection types after expander and irrigated .His quite different in each types either of its shape or its irrigational degree. The intersection types here include the normal function of plane intersection design.
