SETTLEMENTS IN A SAO PAULO SHIELD TUNNEL

The East-West line of the Sao Paulo, Brazil subway system includes about 3.5 km of shield tunnels in the downtown area, about 3 km being completed. The designers (Promon Engenharia S/A) were responsible for the settlement monitoring system, and the data collected was analysed and correlated with characteristics of the soil and the tunnelling methods used. The soil settlement troughs are compared with those predicted by the methods of R.B. Peck and E.J. Cording. The influence of different tail grouting techniques, additional settlements due to the release of air pressure in the tunnel and cases of building damage are described.
