AbatraceFor nearly thirty years, Shanghai has been constructing underground works designed to improve the city's infrastrrcc-
ture. A number ofprojects were undertaken using shield tunnelling method in order to determine whether this method could be used successfully in Shanghai's geology, which is characterized by silt and silty orpuddly clay. These undergroundprojects have included subway tunnels, sewage and water supply tunnels, road tunnels, and offshore discharge tunnels. This paper describes eight subsurface projects in Shanghai that have used the shield tunnelling method successfully.
