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。 Large and medium-sized cities in our country are generally located on both sides of rivers (or the main part is on the same bank). In order to connect with the two sides of the Strait or to cross the border roads, large-sized urban highway bridges with double features of urban bridges and highway bridges need to be constructed. Based on the analysis of the basic characteristics of the layout pattern of bridgeheads in urban highway bridges, this paper discusses the influence of the bridgehead layout patterns on urban planning and bridge usage, which can be used as a reference for the design of urban highway bridges.
