(TU Delft Geo-engineering) Vardon, P.J. (TU Delft Geo-engineering) Hicks, M.A. (TU Delft Geo-engineering) Contributor Vardon, P.J. (editor) Bykov, D. (editor) Date 2016 Abstract A preliminary probabilistic study of the stability of a circular drift excavated for a radioactive waste repository in the French Callovo-Oxfordian claystone is presented and discussed. An analytical mechanical model assuming isotropic elastic behaviour and linear plastic softening was used. Particular emphasis here is placed on the uncertainty of mechanical property values. The test results from several laboratories showed considerably variable property values and they have been interpreted statistically in this investigation. The obtained statistical results were used in a Monte Carlo framework. The performance of the drift was evaluated in terms of the probability of threshold exceedance in the extent of the plastic zone.
