Tunnelling

Research in this area focuses on the following subjects:

Tunnelling in swelling conditions

A new methodology for carrying out triaxial laboratory tests, along with an advanced numerical modeling, was developed by Prof. Marco Barla and was then adopted for the tunnel linings design in rock masses characterized by swelling behavior. The method makes it possible to determine the complete deformation state around the excavation and is described in details in the paper “Numerical simulation of the swelling behaviour around tunnels based on special triaxial tests” published in Tunneling & Underground Space Technology Journal in 2008. Research is still pefomed in this area with respect to laboratory testing and numerical modelling as well as validation on available monitoring data of case studies.

Tunnelling in squeezing conditions

The Shelvip visco-elastic plastic model was developed to assess the required complexity of the law which is able to represent the mechanical behaviour of time dependent behaviour of complex geomaterials satisfactorily (Debernardi 2008). Research is performed to apply the model in different conditions and environments.

Tunnels in overstressed rock masses

The main intent is to analyse the response of TBM excavated tunnels in hard rocks under high in situ stresses, when the failure process is dominated by stress-induced fractures leading to spalling and/or strain bursts. The use of continuum, equivalent continuum and discontinuum models is considered. Also considered is the FDEM combined approach.

Shallow tunneling

Building responses to excavation together with new and advanced monitoring tools are investigated to improve the management of underground construction in congested urban environment.
