<p>A large-size creeping natural slope was simulated with the Finite Element (FE) method, using a visco-hypoplastic material model, which describes the mechanical behaviour of cohesive soils, allowing for viscous effects (i.e. creep, relaxation and rate-dependence ...

<p>Principal geotechnical difficulties likely to be encountered when driving a tunnel through a fault zone are: instability of the face; excessive overbreak and deformation from squeezing and/or swelling fault rocks; instability of intermediate construction ...
