Pore-pressure coefficients for unsaturated soils: generalized effective stress approach
Lyesse Laloui, Alessio Ferrari, Angelica Tuttolomondo
Geotechnical problems with total stress changes occurring rapidly relative to the soil consolidation time can be conveniently addressed using an effective stress-based approach. For saturated states, analytical formulations of pore-pressure coefficients ad ...
CANADIAN SCIENCE PUBLISHING2023Life cycle environmental assessment of retaining walls in unsaturated soils
Alessio Ferrari, Gianluca Speranza
Retaining structures above groundwater level support soils that are usually in a state of partial saturation and subject to the actions of atmospheric agents. The current design approach considers the possible extremes of soil conditions - either totally d ...
ELSEVIER2022Microstructure observations in compacted clays subjected to thermal loading
Lyesse Laloui, Melis Sütman, Roba Houhou
The response of clayey materials to thermal variation has been the subject of extensive studies, given the wide range of engineering applications which involve subjecting soils to substantial temperature fluctuations. A number of hypotheses have been propo ...
ELSEVIER2021On predicting pore fluid pressure changes in unsaturated porous media subject to undrained processes
Lyesse Laloui, Alessio Ferrari, Angelica Tuttolomondo
Predicting the induced change of fluid pressure in an unsaturated porous medium during undrained loading/unloading processes is challenging because two different fluids (a liquid and a gaseous solution) and a mixture of solid particles are involved. The re ...
2021SoilKsatDB: global database of soil saturated hydraulic conductivity measurements for geoscience applications
The saturated soil hydraulic conductivity (Ksat) is a key parameter in many hydrological and climate models. Ksat values are primarily determined from basic soil properties and may vary over several orders of magnitude. Despite the availability of Ksat dat ...
2021Numerical simulation of a layered elastic system using the boundaty element method
The aim of this project is to implement a boundary element method program in order to solve the soil mechanics problem of a two-layered soil subject to a contact on his top surface. For this, I use Python programming language and follow the fictitious elem ...
2020Effects of large macropores on soil evaporation in salt marshes
The occurrence of macropores in salt marsh sediments is a natural and ubiquitous phenomenon. Although they are widely assumed to affect pore-water flow in salt marshes significantly, the mechanisms involved and their extent are not well understood. We cond ...
2020Water retention behaviour of compacted and reconstituted scaly clays
The paper presents the results of an experimental research devoted to investigate the response to suction variations of a scaly clay in compacted and reconstituted conditions. Different experimental techniques (axis translation, vapour equilibrium, dew poi ...
E D P SCIENCES2020Multiphysical behaviour of shales from Northern Switzerland
Shales are involved in energy-related applications such as the extraction of shale gas, the CO2 storage and the nuclear waste disposal. In these contexts, fundamental issues come along with the multiphysical conditions in which shales are found, where mech ...
EPFL2017Numerical modelling of energy piles in saturated sand subjected to thermo-mechanical loads
Lyesse Laloui, Alessandro Francesco Rotta Loria, Chao Shi
This study investigates the impact that different magnitudes and combinations of thermal and axial mechanical loads have on the mechanical behaviour of energy piles in saturated sand. The work is based on the results of a series of thermo-hydro-mechanical ...
