Abstract: Most of the big and medium-sized cities in China are generally located on both sides of rivers or the major parts of some cities are on one side. In order to connect the traffic of each side or to link up the through traffic, it is necessary to build large urban road-highway bridges which are in the dual nature of both urban bridges and highway bridges. Based on analysing the basic features of approach layout of urban road-highway bridge, this paper discusses the influence of approach layout on city planning and the operation of bridges. It can serve as a reference for the design of this kind of bridges.

摘要： 我国大中城市一般均位于江河的两岸(或主要部分在一岸)。为联系两岸交通或沟通过境公路,需修建具有城市桥梁和公路桥梁双重特点的大型城市公路桥梁。本文在分析城市公路桥梁桥头平面布置型式的基本特点的基础上,探讨了桥头平面布置型式对城市规划、桥梁使用的影响,可供设计城市公路桥梁参考。
