Characterization of post-failure movements of landslides in soft sensitive clays

Abstract

Assessment of landslides in soft sensitive clays require, in addition to geometrical aspects, a combined and complete understanding of the engineering properties of the soil materials at their original as well as disintegrated state. In light of the geotechnical characterization of 33 Norwegian landslides, this paper attempts to discuss some of the material properties which influence the extent of post-failure movements of landslides in terms of retrogression and the run-out distance. The energy involved in remolding sensitive clays has been studied for the Norwegian sensitive clays to signify its importance with regards to the estimation of extent of landslides.
