En este trabajo se presenta un estudio realizado como etapa preliminar en el proceso de diseño de un bulto para transporte de Co-60 desarrollado por IMPSA S.A. para la firma Dioxitek S.A., con el objetivo general de verificar las herramientas y modelos numéricos a utilizar en el diseño del bulto. El trabajo tiene como objetivo particular estudiar el asentamiento de la plataforma de impacto usada en los ensayos de caída libre del bulto. Esto implica una adecuada modelación del suelo, del cual se dispone de resultados de estudios geofísicos y propiedades mecánicas. Se analizan y comparan los resultados de un modelo de Mohr Coulomb con un modelo elastoplástico de superficies anidadas. Se estudia el efecto de la variación de las propiedades del suelo en profundidad y de las distintas formas de aplicar la aceleración de la gravedad en el asentamiento de la plataforma. Finalmente se compara con resultados experimentales.
