Research on the Analysis of the Impact and Design Control of Undercrossing Existing Lines in an Intercity Railway Section in Fuzhou
In order to discuss the impact of intercity railways crossing existing subway lines,a design practice project of an intercity railway section crossing existing lines in Fuzhou was analyzed.Based on the analysis of the basic situation,engineering geology,and hydrogeology of the project,the impact range and level of the newly constructed line are classified.Conduct finite element software analysis based on the o-verall design concept and the situation of the existing line itself and surrounding areas.Analyze the deformation of surrounding soil,displace-ment of tunnel structure,convergence of clearance and internal forces.Propose design control measures for underpass sections based on anal-ysis results and existing line monitoring data.The measures meet the control requirements of the construction unit for the underpass area of rail transit.
