Design of Shield Tunnel Structures
2019Shield machine is a steel circular protective device or mobile support. It is suitable for tunnel construction in soft aquifers, especially under the riverbed, seabed, and urban residential areas. The underground structure constructed by the shield method can be simply termed as the shield lining.
