Papers by Michael Kavvadas
The presented results focus on the effect of different ground strength, permeability and face pressure on face stability of EPB excavated tunnels. Face stability is assessed through plots of face extrusion (horizontal face displacement) vs. ground strength. Face extrusion is calculated through 3D coupled hydro-mechanical analyses, using advanced critical state plasticity constitutive models (mainly the Modified Cam Clay).
