De certains effets hydromecaniques lors du creusement et de l'exploitation de galeries de stockage en milieu fracture ––– About some hydromecanical effect occuring during digging and exploitation of storage drift into fractured rockmass

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