Load transfer approach for the geotechnical analysis of energy piles in a group with slab

Lyesse Laloui, Elena Ravera, Melis Sütman

Thermally induced group effects characterise closely spaced energy piles. It has been observed experimentally that the behaviour of energy piles subjected to mechanical and thermal loads, in which the piles are located sufficiently close to each other, is ...

A numerical study on the coupled hydro-mechanical behaviour of compacted bentonite

Lyesse Laloui, Alessio Ferrari, Jose Antonio Bosch Llufriu

Understanding the mechanical behaviour of compacted bentonite upon re-saturation is of outmost importance in most designs of nuclear waste disposal repositories. The behaviour of bentonite is characterized by its stress-path dependency and it is typically ...

Water retention behaviour of compacted and reconstituted scaly clays

Alessio Ferrari

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 ...

The shear strength of Opalinus Clay shale in the remoulded state

Alessio Ferrari

The Opalinus Clay shale formation is considered as a potential host geomaterial for the Swiss deep geological repository for radioactive waste. It presents different facies and it is characterised by a multi-scale heterogeneous composition, by a typical fi ...

Rock strength properties of granitic rocks in Yosemite Valley, Yosemite National Park, California

Federica Sandrone, Michel Jaboyedoff

Yosemite National Park, located in the central part of California’s Sierra Nevada mountains, is a glacially carved landscape filled with iconic rock formations such as Cathedral Peak, El Capitan, and Half Dome. Igneous rocks, consisting primarily of variat ...

A new data set of granitic rock strength values from Yosemite Valley, California: applications to rock fall assessment

To explore connections between rock strength and rock falls, we undertook a comprehensive rock mechanics testing program for six granitic rock types in Yosemite Valley (California, USA) where rock falls are a common geomorphic and sometimes hazardous proce ...

Hydro-mechanical behaviour of a sandy silt from a river embankment

Alessio Ferrari

The paper presents the results of an experimental campaign aimed at characterizing the hydro mechanical behaviour of a sandy silt from a river embankment Due to continuous river level fluctuations and changing climatic and environmental conditions, flood e ...

Energy geostructures: anew era for geotechnical engineering practice

Lyesse Laloui, Melis Sütman

Energy geostructuresprovide low carbon, cost-effective and local energy solutions to structures and infrastructures, which opens a new era for the geotechnical engineering practice, by extending the conventional role of geotechnicaldesign to the one of add ...

Impact of Mineralogical Composition on Geotechnical Properties of Opalinus Clay

Lyesse Laloui, Alessio Ferrari, Eleonora Crisci

Opalinus Clay is the selected host geomaterial for the construction of underground geological disposals for radioactive waste in Switzerland. The formation has been studied in several sites, i.e. the Mont Terri laboratory, and several boreholes in the nort ...

Cell-free soil bio-cementation with strength, dilatancy and fabric characterization

Lyesse Laloui, Dimitrios Terzis

A multi-disciplinary approach is adopted in the present work towards investigating bio-cemented geo-materials which extends from sample preparation, to microstructural inspection and mechanical behaviour characterization. We suggest a new way to induce “ce ...

An experimental investigation on the water retention behaviour of a silty soil for the computation of the lateral earth thrust on a retaining wall

Lyesse Laloui, Alessio Ferrari, Gianluca Speranza

Retaining structures often interact with soils in unsaturated conditions and their performance is influenced by environmental actions. Currently, geotechnical analysis and design approaches mainly consider the soils either totally dry or totally saturated. ...
