Abstract: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.
