Pre‐stressed tunnel lining – pushing traditional concepts to new frontiers / Neue Grenzen für passiv vorgespannte Druckstollenauskleidungen

Abstract: Pressure tunnels with pre‐stressed concrete linings are recognised as state‐of‐the‐art technology. Numerous pre‐stressed concrete linings, featuring diameters of up to 6 m, have been successfully implemented over the last few decades.This paper on the Niagara Tunnel Facility Project (NTFP) illustrates how the concept of passive pre‐stressing can be further developed for application in increasingly complex geometrical and geotechnical boundary conditions. The diversion tunnel with an excavation diameter of 14.4… Show more

“…The Queenston Formation is characterised by a high swelling potential and requires a waterproof lining in order to prevent any swelling of the claystone. The nominal thickness of the technically watertight pressure tunnel varies in between 600 and 700 mm [3].…”
