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.
