New basis for the constitutive modelling of aggregated soils

Lyesse Laloui, Laurent Vulliet, Azad Koliji

Natural and compacted soils are usually characterized by aggregation of particles. The mechanical behaviour of these materials depends on soil structure. The oedometric compression tests performed on aggregated samples presented here showed that these mate ...

The advanced non-destructive method of neutron tomography, together with image analysis, is used to evaluate the structural evolution of an aggregated soil during one-dimensional compression tests. Aggregation of primary particles is a commonly observed ph ...

An automated digital image processing technique is presented for the measurement of specimen volume change during triaxial testing. A digital camera is fixed at a constant distance from the triaxial cell. Pictures taken at various intervals are processed ( ...

Current models of the elasto-plastic behaviour of unsaturated soils contain important underlying assumptions that have not been tested due to a lack of adequate experimental data. To address this issue, the objective of this paper is to provide a comprehen ...

Considerations on the design of cut-and-cover tunnels

Aurelio Muttoni, Laurent Vulliet, Vincent Labiouse, Sylvain Plumey

The communication shows an alternative for introducing soil-structure interaction in the analysis of cut-and-cover tunnels. An uncoupled method is illustrated through two examples representative of the situations found in practice. The main features of eac ...

La recherche effectuée sur les tranchées couvertes, ou tunnels exécutés à ciel ouvert, apporte une contribution théorique à la compréhension du comportement de ces ouvrages jusqu’à l’état limite ultime. Une méthode simplifiée inspirée de la méthode converg ...

Rapport OFROU2006

To be able to take effective and efficient decisions leading to transparent and comparable results between different risk situations, a consistent and systematic risk management process has to be followed (in this context called “integral risk management”) ...

In unsaturated soil mechanics testing, total volume change of the specimen is related to both water and air volume changes and cannot be measured with the same techniques as in conventional saturated soil mechanics. Over the years, several methods have bee ...

Plasticity in soil-structure interaction applied to cut-and-cover tunnels

Aurelio Muttoni, Laurent Vulliet, Vincent Labiouse, Sylvain Plumey

Cut-and-cover tunnels behavior at ultimate limit state depends strongly on the interactions between the foundation soil, the backfill and the reinforced concrete structure. Characterization of the potential failure modes of these types of structure necessi ...

Behavior of a dual-purpose pile as foundation and heat exchanger

Lyesse Laloui, Laurent Vulliet

The behaviour of a pile subjected to thermo-mechanical loads was studied in situ with the aim of quantifying the thermal influence on the bearing capacity of heat exchanger piles. To accomplish this, a pile situated in a building under construction was equ ...
