摘　　要：从南京地铁珠-鼓区间软～流塑地层隧道具体工程出发,根据既有地面建筑物基础允许变形的规范要求,建立了施工地表沉降控制基准,同时对隧道施工进行了动态模拟计算和分析,并通过施工现场监测结果,对所获得的成果进行了验证.Based on the construction of subway tunnel and permissible displacement of buildings by according to the correlative specifications, a method is put forward to establishing ground surface settlement controlling criterion for shallow buried tunnels in soft-flow plasticity strata between Zhu\|Gu in Nanjing. By numerical calculation, the ground surface settlement changing during the excavating is discussed. And the results are validated by field measurement.
