Abstract
The mechanism of initiation or triggering of landslides in soft sensitive clays is governed by strain softening and localization of deformation into thin shear bands. The triggering load and the extent of the initial part of the landslide depend upon the formation and propagation of these shear bands and in particular upon their thickness. The role of local pore water drainage and rate dependency in the formation and propagation of these shear bands is not fully understood. This paper reviews some of the research carried out during the last decades within this field, discuss the results and points to some recommendations for further research in order to reach a conclusion.
