Document Type: Proceeding Paper

Part of: Shotcrete for Underground Support V

Abstract: When designing tunnel support the key question is to determine the loading conditions resulting from the deformation of the rock mass during and after excavation. Principle views are given on how to evaluate the rock load, the behaviour of a shotcrete lining and its interaction with the deforming rock mass.
