- In a recently developed model for fracture dilation during grouting, the fracture stiffness and deformation for in situ conditions is approximated using a minimum of geometrical input. The model describes the loading and unloading behaviour of mated and unmated fractures and predicts a rapid change in stiffness at a critical grouting pressure. In this paper, the implications of this model on real world grouting performance are explored, and the possible implications on grouting design and sealing efficiency is discussed. Data from the construction of a railway tunnel in Sweden (Botniabanan) has been re-evaluated using the new model, showing support for the interpretations regarding the principal behaviour of the rock mass during grouting.
