Micromechanical modelling of suffusion: towards the stability analysis of hydraulic structures.

Modélisation micromécanique de la suffusion : vers une analyse de la stabilité des ouvrages hydrauliques.

Résumé

Suffusion is the most controversial of the process of internal erosion and piping as there is a lack of microscopic understanding of the degradation processes at stake in saturated soils subjected to an internal flow. Thanks to the use of a DEM-PFV (Discrete Element Method - Pore-scale Finite Volume) approach, this study addresses the fully coupled problem of the suffusion of a non cohesive granular material. Eligible particles to grain detachment and grain transport are characterized from a micromechanical point of view thanks to the use of an enhanced force chain definition and the definition of a pore network. A Representative Elementary Volume with respect to the grain detachment and grain transport is then quantified.
