城市桥梁邻近既有高速铁路隧道工程设计要点分析——以解放大街工程为例

通过对新建桥梁工程边界条件、与铁路安全相关的工程控制标准的理论计算、施工及运营期监测、其他铁路防护措施等几个方面的探讨，同时结合解放大街实际工程的建设情况，简要总结了新建城市桥梁工程邻近既有高速铁路隧道工程的设计要点，为类似工程在设计、施工、运营阶段提供参考。

Analysis on Design Essentials of Urban Bridge Close to Existing High-speed Railway Tunnel for Jiefang Avenue Project

By discussing the boundary conditions of newly built bridge project, the theoretical calculation of the engineering control standards related to the railway safety, the monitoring of construction period and operation period and the other railway prevention measures, and combined with the actual engineering construction situation of Jiefang Avenue, the design essentials of the new urban bridge project close to the existing high-speed railway tunnel project are summarized briefly, which can be referenced for the design, construction and operation periods of the similar projects.
