以南昌市八一广场地铁旁的一个古建筑物为研究对象，通过建立包含4孔隧道的轨道-隧道-大地-建筑物三维有限元模型，进行模态分析和瞬态动力学分析。计算1、2号线单独运行及1、2号线同时运行三种情况下的建筑物振动。结果表明：埋深较浅的2号线对建筑物振动影响较大；只有当1号线和2号线同时运行时，建筑物振动才会超过限值，但超标量不大；随楼层上升，建筑物水平振动呈减小趋势，但在顶层却有最大值。

Taking a historic building near the subway of Nanchang Bayi Square as the research object, a three-dimensional finite element model of rail-tunnel-ground-building including four tunnels is constructed and the modal and transient dynamics analyses are conducted. Three situations, line 1 in operation, line 2 in operation and line 1 and line 2 in operation at the same time, are considered and their building vibration responses are calculated respectively. The results show that line 2 with shallow depth has a greater influence on the building vibration than line 1 does. Building vibration value exceeds the limit value a little bit only when the line 1 and line 2 are in operation at the same time. With the floor rising, building horizontal vibration decreases but its maximum value appears on the top floor.
