Abstract

ESCOLANO-SANCHEZ, Félix; BUENO-AGUADO, Manuel  and  SERNA, Alberto Mazariegos-de la. Use of constitutive equations by Hardening Soil Model for the characterization of the Blue Guadalquivir Marls from pressuremeter tests. Dyna rev.fac.nac.minas [online]. 2017, vol.84, n.201, pp.109-116. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v84n201.56415.

The pressuremeter test performed in boreholes has proven itself to be as a useful tool in geotechnical studies. A use of it is the comparison of its results with those obtained from a mathematical model ruled by a soil representative constitutive equation constitutes one of its main applications. In this paper a numerical model of concentric rings, governed by the constitutive equation of the Hardening Soil Model, is has been shown. This model could be a framework for the interpretation of this test. The model analyzes some variables such as: the type of response, the initial state, the drainage regime and the constitutive equations, so it can be applied to any geological formation that has a representative number of tests.

Keywords : Geotechnical parameters; Hardening soil Model; pressuremeter tests; constitutive equations.
