与地铁盾构（车站）相关的城市桥梁方案设计

摘要:

以上海市近十几年的市政工程为背景,总结整理与地铁相关的城市桥梁布置方案设计。并经相关沉降位移计算,在满足轨道交通的相关安全要求前提下,确定新建城市桥梁的桩基与地铁盾构的安全净距,从而进一步合理布置桥梁横断面、合理布置桩基、合理选用上下部结构形式。

Abstract:

On the basis of municipal engineering in Shanghai in the last decade, the project design of the urban bridge layout which is related to subway is summarized. Settlement displacement calculated and safety requirement on rail transit met with, the safety clearance between the pile foundations for newly-built urban bridges and the subway shields are determined, and then the cross sections of the bridges have been laid out reasonably, pile foundations have been arranged reasonably and the superstrcture and substrcture form has been chosen reasonably.
