THE SYDNEY HARBOUR TUNNEL VENTILATION STATION: THE FACTORS INFLUENCING ITS DESIGN AND ROLE AS THE PHYSICAL INTERFACE BETWEEN THE NORTH SHORE DRIVEN TUNNELS AND THE IMMERSED TUBE UNITS. SEVENTH AUSTRALIAN TUNNELLING CONFERENCE; THE UNDERGROUND DOMAIN, SYDNEY, 11-13 SEPTEMBER 1990; PREPRINTS OF PAPERS

The Tunnel Ventilation Station of the Sydney Harbour Tunnel forms the interface between the North Shore Driven Tunnels and the Immersed Tube Units within Bradfield Park on the northern foreshore of Sydney Harbour. The development of the adopted structural concept was influenced primarily by site geology, the problems of buoyancy and the overall construction sequence for the three structures within Bradfield Park. The structural scheme adopted was a fully drained, free standing structure incorporating vertical and horizontal cut-off walls together with a rock depressurisation well system. This structure addressed the influencing factors as well as facilitating continuity to the tunnel construction programme whilst minimising construction interdependencies within Bradfield Park.
