The design of underground facilities in rock salt relies on constitutive models whose
parameters are derived from laboratory tests and (when possible) recalibrated on the basis …

The main purpose of this paper is to analyze the convergence measurements in drifts of the
Underground Research Laboratory (URL) of the French National Radioactive Waste …

In this study, we analyzed the influence of the excavation size and the sequence of
excavation on the convergence evolution in drifts excavated in Callovo-Oxfordian claystone …

In drained compression tests, saturated specimens of claystone, collected by ANDRA (the
French agency in charge of the management of radioactive waste disposal) from samples …

To better describe excavation operations in deep geological formations, several aspects
should be considered, especially the material anisotropy, time-dependent behavior, and …

Permeability and its spatial distribution around an underground opening in a geological
formation are important for the interpretation of thermal, hydraulic and mechanical findings …

The French National Radioactive Waste Management Agency (Andra) began in 2000 the
construction of an Underground Research Laboratory (URL) with the main goal of …

Convergence measurements recorded for one representative micro-tunnel (diameter c. 0.7
m) in Callovo-Oxfordian claystone were analysed. The micro-tunnel was excavated in the …

Prédire l'évolution de la perméabilité avec la fissuration constitue un objectif primordial afin
d'évaluer les conséquences d'un chargement mécanique sur la durabilité et l'étanchéité des …

The present work explores the numerical modelling of the hydro-mechanical behaviour of
the fractured zone in deep nuclear waste disposal schemes. This includes simulation of …
