Resumen:
Geomaterials are mixtures of solids with voids which are filled by fluids such as air and water. Due to the strong coupling between phases, pore pressures can be generated if loading is applied fast enough. In the case of loose metastable materials, unstable behavior and catastrophic failure can happen. An important case is that of fast catastrophic landslides with large velocities caused by high pore pressures in their lower part. The purpose of this paper is to present mathematical, constitutive and rheological models which describe the most relevant phenomena, together with discretization techniques.
