Abstract

This article is devoted to the modelling of interdependent mechanical and hydraulic behaviours of geomaterials in presence of a single throughwall fracture by means of micromechanics arguments Experimental results of fractured concrete samples show nonlinear evolutions for both mechanical and hydraulic behaviours with respect to confinement intensity These nonlinear responses are interpreted by the progressive closure of cracklike pores defining the pore volume of the fracture interfacial domain Disregarding tortuosity effects we adopt a 2D representation for these cracks The key role of the fracture initial porosity is also emphasized It allows to discuss the shape of the distribution of the local apertures distribution function classically used intercepted here in terms of the distribution of initial crack–aspect ratio within the fracture domain Application on fractured concrete samples shows the capability of the theoretical model to accurately reproduce the experimental results
