Influencia de la densidad de volumen en parámetros elastoplásticos empleados para la modelación de la compactación del suelo.

The constitutive models of critical state are among the most employed for soil compaction simulation by means of finite element method. This paper has the objective to determine the influence of soil bulk density on elastoplastic parameters of Rhodic Ferralsol soil. Triaxial and compression uniaxial tests were carried out to remoulded samples, with a bulk density of 1.1; 1.175; 1.25 Mg m-3, and gravimetric moisture content of 25 kg g-1. The obtained values of variables analyzed can be used as input data to modeling soil compaction by finite element method and allow to know critical state variables behaviour of one of the Cuban soils with major economic importance.
