大跨度密贴上穿既有地铁结构变形影响分析

Analysis on the Deformation Influence of Construction Method of Large Span Close Paste over Across Existing Subway

新建车站为换乘车站,大跨度密贴上穿既有线,在现状调查和检测的基础上,论文采用数值模拟的方法,模拟上穿段施工对既有地铁结构的影响,根据计算结果,分析既有地铁结构及轨道结构的变形,对施工提出相关要求,并采取相应的轨道防护措施,以保证运营安全。

A new station for transfer, large-span close paste over across existing lines, on the basis of the present situation investigation and detection, This paper adopts the method of numerical simulation to simulate the influence of the over across construction on the existing subway structure, analyzes the deformation of the existing subway structure and track structure according to the calculation results, puts forward the relevant requirements for the construction, and takes the corresponding track protection measures to ensure the operation safety.
