摘　　要：通过有限元数值模拟与实际监测数据的对比研究,结合两条盾构推进参数及注浆参数的不同比较,对某地铁两条盾构先后穿越同一栋建筑物的沉降变形控制做出了初步分析,为地铁盾构在同类地层穿越建筑物期间控制变形提供参考。Based on the comparative research on finite element simulation results and field survey data,this paper draws the preliminary conclusion on the settlement control of a building crossed successively by two shield tunnels with their different advancing and grouting parameters taken into consideration,which can provide reference to other similar cases in the same stratum.

关 键 词：盾构 沉降控制 监测
