Centrifuga geotécnica

Abstract

The centrifuge modelling is a technique that studies clifferent geotechnical processes (consolidation, deforma-tion, failure types, etc.) by constructing a small scak model of an actual prototype and subject it in a centrifuge tú accekration fields much greater than gravity over a short period compared to the fidl-scale effects. The aim of centrifuge modeling is a correct reproduction of the real geotechnical pmblem. Scaling laws are es-tablished tú relate the behavior of the prototype with the real moda Centrifuge modeling tests are an important tool available in geotechnical engineering, to study, analyze and design real geotechnical problems. A centrifuge is essentially a sophisticated device for testing complex geotechni-cal structures obtaining results that can be extrapolated tú a real prototype. Geotechnical centrifuges are classified in two gro upe according tú their configuration: the rotating-arm type and the drum type. The first group is broadly spread compared to the drum type, since they have a higher loading capacity, providing construction of a model and its subsequent instrumentation.
