为了解决改建道路对既有运营铁路的安全评估问题,以上海市浦星公路(南行港路-人民塘路)改建工程下穿浦东铁路为研究对象,在分析现状道路与既有线铁路的交叉关系基础上,提出改扩建工程方案,并运用数值模拟方法,研究了改扩建道路在施工阶段和全断面运营阶段对既有铁路线结构变形的影响.研究结果表明,改扩建道路在施工阶段和全断面运营阶段对既有铁路线结构的变形影响均不超过2 mm,在规范的控制范围内.
A Study on the Deformation Influence of Reconstructed Roads Undercrossing Existing High Speed Railway Bridge Structures
In order to solve the safety assessment problem of the reconstructed road on the existing oper-ating railway,the Pudong Railway under the reconstruction project of Shanghai Puxing Highway(Nanxinggang Road to Renmingtang Road)was taken as the research object.Based on the analysis of the intersection rela-tionship between the current road and the existing railway,a reconstruction and expansion project plan was proposed,and numerical simulation methods were used,Studied the impact of road reconstruction and expan-sion on the structural deformation of existing railway lines during the construction phase and full section op-eration phase.The research results indicate that the deformation of the existing railway line structure during the construction and full section operation stages of the reconstructed and expanded roads does not exceed 2 mm,and within the standard control range.
