Image-based measurements of degree of saturation
(E3S Web of Conferences, 2020)
Conference report
Open AccessA method based on SWIR images is proposed for measuring the degree of saturation in soils. This method is especially suitable for use in experiments conducted in the facilities of a common geotechnical laboratory. The ... -
Modelling acid attack of oilwell cement exposed to carbonated brine: effect of specimen geometry on experimental results
(2019)
Conference report
Open AccessIn recent years, the authors and co-workers have developed a diffusion-reaction model for the degradation process of oilwell cements exposed to carbonated brines in the context of CO2 capture and storage in abandoned oil ... -
Viscoplastic constitutive models for zero-thickness interface elements, formulation and applications
(2019)
Conference report
Open AccessAn energy-based work-softening visco-plastic model for zero-thickness interface elements has been developed as an extension of an existing elastic-perfectly-viscoplastic formulation. In the inviscid limit the model also ... -
Coupled THM analysis of long-term anisotropic convergence in the full-scale micro tunnel excavated in the Callovo-Oxfordian argillite
(International Centre for Numerical Methods in Engineering (CIMNE), 2019)
Conference report
Open AccessThe main purpose of this paper is to analyse the convergence measurements of the ALC1604 in situ heating test carried out in the Callovo-Oxfordian claystone formation (COx) in the Meuse/Haute-Marne underground research ... -
A zero-thickness mortar / Interface formulation with application to fracture mechanics
(2019)
Conference report
Open AccessA zero-thickness mortar/interface element formulation is briefly described and demonstrated. This element may be considered as an extension of traditional zero-thickness interface element, in order to represent material ... -
Thermo-hydro-mechanical simulation of a full-scale steel-lined micro-tunnel excavated in the Callovo-Oxfordian claystone
(2019)
Conference report
Open AccessThe paper presents an interpretation of the full-scale ALC1604 in situ heating test carried out in Callovo-Oxfordian claystone (COx) in the Meuse/Haute-Marne underground research laboratory (MHM URL). The MHM URL is a ... -
Coupled thermo-hydro-mechanical behaviour of a deep clay
(EDP Sciences, 2019)
Conference report
Open AccessAn experimental study on Ypresian clays –one of the potential deep formations in Belgium for the geological disposal of heat-emitting radioactive waste– was undertaken to systematically study its thermal properties and ... -
Multi-scale effects on the hydraulic behaviour of a root-permeated and compacted soil
(EDP Sciences, 2019)
Conference report
Open AccessWhile roots have been generally proved to be beneficial to soil mechanical behaviour, different and counterposed results have been found when investigating their effects on soil hydraulic response. Roots affect the ... -
Zero-thickness interface model with chemical degradation by acid attack
(2019)
Conference report
Open AccessCarbon dioxide (CO2) storage in abandoned oil/gas reservoirs is considered a viable alternative to reduce greenhouse gas emissions to the atmosphere. An important element of the risk associated with long-term CO2 storage ... -
Soil surface boundary condition in desiccating soils
(The Icelandic Geotechnical Society (IGS), 2019)
Conference report
Restricted access - publisher's policySoils undergoing desiccation exhibit shrinkage and eventually cracking. That may become an environmental problem in practical applications. From a Geotechnical perspective, it is possible to solve the corresponding ... -
Monitoring of rainfall and soil moisture at the Rebaixader catchment (Central Pyrenees)
(Association of Environmental & Engineering Geologists (AEG), 2019)
Conference report
Open AccessThe instrumental monitoring of torrential catchments is a fundamental research task and provides necessary information to improve our understanding on the mechanisms of debris flows. While most monitoring sites include ... -
Comparison of several geomatic techniques for rockfall monitoring
(2019)
Conference report
Open AccessRockfalls are slope instabilities very frequent and harmful in mountainous areas. They cause damage in infrastructures (roads and railways), buildings, vehicles and people.Several testswerecarried out to ...
