摘要
Abstract
In order to study the impact of construction loads on existing shield tunneld,this study takes the construction of the tie beam at the railway-related pile location in Contract Section A1 of the first phase project of Fuzhou Binhai New City Expressway as a case.The finite element software midas GTS NX was employed for numerical simulation,aiming to analyze the additional stress imposed on the shallow-buried existing shield tunnel and the consequent lining displacement during the tie beam construction process.Based on the simulation results,an assessment was made to determine whether the tie beam construction scheme complies with relevant specifi-cations,thereby ensuring the safe operation of the existing tunnel.关键词
