This paper presents a generalized rigorous and simple large strain solution for the undrained expansion of a vertical cylindrical cavity in critical state soils using a rate based plasticity formulation: the initial stress field is taken as anisotrop

This paper generalizes the finite strain Coulomb solution of Vrakas and Anagnostou (Int J Numer Anal Meth Geomech 2014; 38(11): 1131–1148) for the classic tunnel mechanics problem of the ground response curve to elastoplastic grounds satisfying a n

The instantaneous response of saturated low permeability grounds to tunnel excavation is important for deformations and stability close to the tunnel face. It is characterized by zero volume change in combination with the development of excess pore p

The ground response to tunnel excavation is usually described in terms of the characteristic line of the ground (also called ‘ground response curve’ GRC) which relates the support pressure to the displacement of the tunnel wall. Under heavily squ

The small strain assumption routinely made in tunnel analyses remains sufficient from an engineering point of view as long as wall convergences do not exceed 10. Although convergences are indeed less than 10 in the great majority of tunnelling projec
