本文以上海浦尔新区张家浜虹盛路桥总体设计为例,分析了城市既跨路又跨河的城市桥梁总体设计特点及需考虑的各方面因素,既要考虑城市规划、现场条件,还要考虑跨越道路的功能、等级、通行能力和跨越河道的行洪排水、通航等级,并对桥型、线形选择及桥宽、跨径、梁底标高确定因素进行分析和探讨,对桥梁基本结构设计进行简要介绍。 Taking the overall design of Hongsheng Road and Bridge in Zhangjiagang, Pu'er New District, Shanghai as an example, this paper analyzes the overall design features of urban bridges and the factors that need to be considered in the urban bridges both across the river and the river. It is necessary to consider the urban planning, site conditions, It is necessary to consider the function, grade, capacity of crossing the road and the level of drainage, navigation and navigation across the watercourse, and to analyze and determine the factors that determine the bridge shape, line shape, bridge width, span and elevation of the bottom of the bridge. Design for a brief introduction.
