THE STOCKHOLM UNDERGROUND

The paper summarizes the drill-and-blast techniques of excavation used in constructing the underground railway public transport system of Stockholm. The Stockholm Tunnelbana now totals 110 km of rail including 53 km in rock tunnels. The paper treats drill-and-blast methods, stability requirements, methods of controlled blasting to obtain stability and avoid damage to structures, and methods and requirements for ground water control in urban areas. Recent underground stations on the Jaerva line have been given a new design in which the traditional cast concrete ceiling has been discarded. The rock ceiling is exposed by a thin (7.5-10 cm) layer of reinforced shotcrete only. In some station walls the bare beautiful rock surface itself is exposed and is utilized as a decorative work of art. The number of the covering abstract of the conference is IRRD 231024.
