浅埋暗挖法隧道在软～流塑地层中下穿建筑物施工技术

Constrution Technology of Shallow-buried Excavation Method through Structure in Soft Fluidity Plastic Ground

南京地铁一号线南延线花神庙站～南京南站区间隧道部分区段位于软～流塑地层中,隧道上方有建筑物,施工采用了超前大管棚、超前径向注浆小导管、掌子面注浆等强支护措施,采用监控量测的信息化技术,确保了隧道及地面建筑物的安全。

The tunnel between the Huashenmiao station and Nanjing south station of Nanjing No.1 subway line is located in soft fluidity plastic ground.There are some buildings on the top of the tunnel.It is using large-scale piperoof the small ahead-grouting pipe and tunnel face grouting technology to make strong protection,and using Monitoring and Measurement technology to make sure the tunnel and structures safe.
