The advantages of multicriteria analysis for diagnosis of internal erosion phenomena

摘要

Over the last ten years the Compagnie Nationale du Rhone, part of the energy branch France of Groupe GDF/SUEZ, in partnership with EDO (Europeenne de Geophysique), has developed novel techniques to facilitate understanding of the behaviour of soils and flows. This communication presents the case of a dike under load, subject to internal erosion. Its behaviour was determined by a multicriteria analysis based on different in situ investigation methods and a novel method, geophysical tracing.
