An eulerian model for soil dynamics: application to fast slope movements

ABSTRACT

This paper presents a theoretical framework to model soil behaviour under dynamic conditions. The equations describing the coupling between the solid skeleton and the pore fluids are presented following an eulerian approach based on the mixture theory that can provide an unified formulation for both initiation and propagation phases of fast landslides, such as avalanches of rocks and granular materials, flowslides and debris flows.
