The construction of the Domed Stadium in Toronto necessitated the relocation of the John Street Pumping Station and associated water supply tunnels for the downtown Toronto area. The proposed structures include tunnels, shafts, and a new pumping station built in or founded on rock. The shale rock of the Georgian Bay formation is known to possess high horizontal stresses and time-dependent deformation and at this site contains numerous horizontal fractures filled with clay seams. This paper presents the results of the site investigation, field and laboratory testing, analysis, and design for the buried structures. Special provisions for "rock squeeze" for different structures are also described.Key words: tunnels, shafts, shale, squeezing rock, horizontal stress, rock–structure–time interaction.
