De certains effets hydromécaniques lors du creusement et de l'exploitation de galeries de stockage en milieu fracturé

Abstract : This article deals with the analysis of hydraulic behaviour of storage works excavated in fractured rock using numerical modelling.The 3D distinct element code 3DEC is used to assess the variations of water pressure, displacement, stress, flow-rate in the fractures intersected by a circular gallery.We could show the importance of the mechanical effects, and then quantify the sensitivity of the results to the localization, the stiffness and the orientation of the fractures.
