Estructuras sedimentarias de deformación (sismitas) inducidas por licuefacción con un simulador de terremotos

Abstract

This study is a first attempt to reproduce se¡smites in laboratory using a shaking table and natural sediments. The deformation linked to liquefaction-fluidization processes has been analysed, contlnously controlling the Interstitial pressure and acceleration. Morphologically, two main types of structures have been observed: fluid escape and load. The morphological variety is primarily controlled by the type of sedimentary column
