Modelling of Landslides: (II) Propagation

A depth‐integrated, coupled SPH model for flow‐like landslides and related phenomena

“…Here we can mention the work of Hutchinson [41], who proposed a sliding consolidation model to predict run out of landslides, Iverson and Denlinger [42], Pastor et al [4,43] and Quecedo et al [44].…”

“…This approach has been used by Iverson and Denlinger [42] and Pastor et al [43]. The equations of the propagation-consolidation model are…”

A depth-integrated viscoplastic model for dilatant saturated cohesive-frictional fluidized mixtures: Application to fast catastrophic landslides

“…In the case of fluidized geomaterials, this theoretical framework has not been applied until recently. We can mention here the work of Hutchinson and Prager [19] who proposed a sliding consolidation model to predict run out of landslides, Iverson and Denlinger [27], Pastor et al [42][43][44][45] and Quecedo et al [47]. This section is devoted to derive a coupled depth-integrated model from the velocity-pressure model of Zienkiewicz.…”

“…Coupling between solid particles and pore fluids has been investigated in Geomechanics since the early work of Biot [5], and considerable progress has been achieved [6,8,13,35,[50][51][52]. Concerning the propagation phase, the study of coupling has been developed at a later stage [22,[25][26][27]43].…”

“…This mechanism of failure is associated to concepts such as material softening, strain localization and shear bands. Flows are usually produced in loose metastable deposits, where failure is of diffuse type [14,43]. The tendency of the soil to compact results on the generation of high pore pressures and a decrease of the effective confining pressure which causes in some cases liquefaction.…”
