Aplicación de ensayos de centrífuga en distintas técnicas de mejora del terreno

Abstract

Centrifuge modeling is a physical method that consists of a construction of a scale model of a real prototype, in order to reproduce the actual geotechnical problem, to place it afterwards in a centrifuge so as to simulate artificially new gravity forces which are higher than those of the Earth. This speeds up timely geotechnical processes such as consolidation, deformations, failures, settlements, etc. The reproduction of complex soil behaviour is the goal of centrifuge modeling. Substitute materials can be used to make reliable interpretations. There are scaling laws that correlate the behaviour of a model with that of the prototype. This paper aims to undertake a review of several case studies, published in geotechnical literature, where the use of geotechnical centrifuge applied to different ground improvement techniques is detailed. The characteristics of the centrifuge machine, preparation and implementation of the samples and the results are explained in each point.
