SETTLEMENT AND FACE STABILITY BORING OF A LARGE TUNNEL. PROCEEDINGS OF THE ELEVENTH INTERNATIONAL CONFERENCE ON SOIL MECHANICS AND FOUNDATION ENGINEERING, SAN FRANCISCO, 12-16 AUGUST 1985

Various computation methods were adopted to analyse the subsidence induced by the excavation of a large-diameter urban tunnel using a hydroshield machine. A comparison of these data with the deformations measured at the surface confirmed the validity of their distribution according to a normal probability curve. It was also possible to discriminate between the amount of deformation caused by the annular gap between soil and lining and the amount due to face yielding. A correlation was established between the latter and the stability factor of the tunnel face. For the covering abstract of the conference see IRRD 287689. (Author/TRRL)
