This study presents numerical and experimental models for the analysis of the excavation of soft soils by means of a cutting tool. The computational model is constructed using an Updated Lagrangean (UL) velocity-based Finite Element approach. A hypop

The mechanized tunnel construction is carried out by tunnel boring machines, in which the soil in front of the working face is removed, and the tunnel lining is carried out with shotcrete or the setting of segments and their back injection. Advanceme

A numerical model based on the particle finite element method (PFEM) combined with a hypoplastic constitutive model is proposed for the analysis of soft soil excavations by means of single and multiple excavation tools. The PFEM allows to efficiently

9th edition of the International Conference on Computational Methods for Coupled Problems in Science and Engineering.
A coupled solid velocity-water pressure (vp) Particle Finite Element (PFEM) formulation in conjunction with a hypoplastic model for sandy soils is presented. Large deformations of the soil and the ever-evolving topology of the ground free surface, ke
