New models linking piezometric levels and displacements in a landslide

摘要

The aim of this article is to present two models linking the piezometric level to the displacementsof a landslide. These two relations are validated with the study of the Petit Caporal landslide (Boulogne-sur-Mer,France). The obtained results are very correct since both models manage to follow the evolution of thedisplacements. These relations stem from two distinct approaches: the first one based on experimental conceptsand the second one based on the study of creep. These models are relevant alert systems,able to detect changesin the move of the slide. Their easy use encourages to validate them on other sites and to generalise this kind ofstudies to other unstable slopes.
