摘　　要：利用岩土有限元软件PLAXIS 3D,济南市轨道交通R2线一期工程历~二区间隧道下穿胶济铁路客运专线引起胶济客专八涧堡特大桥桥墩墩顶最大横桥向累加位移、最大顺桥向累加位移、最大竖向累加位移;引起桥墩承台顶最大横桥向累加位移、最大顺桥向累加位移、最大竖向累加位移;引起胶济普铁股道1最大沉降量、股道2最大沉降量股道3最大沉降量、股道4最大沉降量、股道5最大沉降量。均符合控制值标准。Using the geotechnical finite element software PLAXIS 3D,the first phase of Jinan Rail Transit R2 Line Project Li-2 Section Tunnel underpasses the Jiaoji Railway Passenger Dedicated Line,causing the largest cross-bridge pier top of the Bajianbao Bridge of Jiaoji Passenger Dedicated Railway to accumulate Displacement,the maximum cumulative displacement along the bridge,and the maximum vertical cumulative displacement;cause the maximum lateral cumulative displacement,the maximum along the bridge cumulative displacement,and the maximum vertical cumulative displacement on the top of the pier cap;cause the maximum settlement of Jiaojipu Railroad 1 The maximum settlement of strand 2 is the largest settlement of strand 3,the largest settlement of strand 4,the largest settlement of strand 5.All meet the control value standard.
