Coupled solid-fluid response of deep tunnels excavated in saturated rock masses with a time-dependent plastic behaviour
(2021-12)
Article
Open AccessThis article provides a general numerical approach for modelling the response of deep tunnels excavated in saturated time-dependent plastic rock masses, considering a coupled solid-fluid interaction and time-dependent ... -
THM analysis of a soil drying test in an environmental chamber: the role of boundary conditions
(Elsevier, 2022-01)
Article
Open AccessThis paper presents the numerical analysis of an experimental soil drying test carried on an initially slurry soil specimen with controlled temperature and relative humidity in a laboratory environmental chamber. The imposed ... -
Benchmark study of simulators for thermo-hydraulic modelling of low enthalpy geothermal processes
(2021-11)
Article
Open AccessIn order to assess the thermo-hydraulic modelling capabilities of various geothermal simulators, a comparative test suite was created, consisting of a set of cases designed with conditions relevant to the low-enthalpy range ... -
Homogenización de barreras de arcilla para residuos nucleares
(2021-07)
Article
Open AccessLas funciones de seguridad de las barreras de bentonita para residuos nucleares dependen principalmente del valor de su densidad seca (o porosidad). La evolución de esta variable durante la fase transitoria de la barrera ... -
Modelling methane hydrate saturation in pores: capillary inhibition effects
(2021-09)
Article
Open AccessExperimental and field observations evidence the effects of capillarity in narrow pores on inhibiting the thermodynamic stability of gas hydrates and controlling their saturation. Thus, precise estimates of the gas hydrate ... -
A full-scale in situ heating test in Callovo-Oxfordian claystone: observations, analysis and interpretation
(Elsevier, 2021-05)
Article
Restricted access - publisher's policyThe paper describes the performance, observations and numerical interpretation of a full-scale in situ heating test conducted on Callovo-Oxfordian (COx) claystone in the Meuse / Haute-Marne (MHM) Underground Research ... -
Effect of microstructure and relative humidity on strength and creep of gypsum
(2021-08)
Article
Open AccessThe wide range of gypsum facies observed all over the world and the strong heterogeneity that may be present even within a single facies often cause an inhomogeneous mechanical response that, if neglected, may be particularly ... -
Analysis of cone penetration in brittle liquefiable soils
(Elsevier, 2021-06)
Article
Restricted access - publisher's policyThe paper presents a comprehensive set of simulations of the cone penetration test with pore pressure measurements (CPTu test) in brittle, potentially liquefiable, soils using advanced numerical techniques. The large ... -
Analysis of the process of compaction movements of deposits of crushed salt tailings
(2021-11)
Article

Experimental analysis of desiccation cracks on a clayey silt from a large-scale test in natural conditions
(2021-07)
Article
Restricted access - publisher's policyThis paper presents an experimental investigation on the impact of environmental variables on soil cracking in natural conditions. The test was performed on a large soil specimen of initial size 3 × 3 × 0.5 m exposed to ... -
A contact model for rough crushable sand
(2021-06)
Article
Open AccessSand roughness is now accessible to measurement. Incorporating this parameter into sand models using the discrete element method (DEM) is known to improve bulk small strain response. In this work we explore the effect on ... -
DEM examination of SPT correction factors
(2021-06)
Article
Open AccessThe Standard Penetration Test (SPT) is the most widely used method for dynamic testing of soils. The test is simple and robust but difficult to control and not fully standardized. As a result, experimental results typically ...
