以福州地铁l号线的罗汉山站—福州火车站区间段盾构隧道工程为依托,采用有限元程序MIDAS,对近距离双线平行盾构掘进过程进行动态模拟,揭示盾构新隧道施工对既有铁路轨道和排洪涵管沉降产生的影响,得到了铁路轨道和涵管沉降曲线。计算结果表明,列车数量、隧道注浆程度、地层损失率等因素对铁路轨道和排洪涵管沉降有较大影响。

The shield boring of twin-tube tunnels is dynamically simulated by means of finite element software MIDAS, with the boring of Luohanshan station-Fuzhou Railway station section on No. 1 line of Fuzhou Metro as an example. The influence on the existing railway tracks and drainage culverts induced by shield boring is presented. The deformation curves of the railway tracks and drainage culverts are obtained. The calculation results show that the quantities of the trains, the tunnel grouting effect and the ground loss ratio have serious influence on the settlement of the railway tracks and drainage culverts.
