Los ensayos presiométricos ejecutados en sondeos han demostrado ser una herramienta eficaz en los estudios geotécnicos destinados a obras de infraestructura civil. Un aprovechamiento intenso del mismo, consiste en la comparación de sus resultados con los obtenidos de un modelo matemático gobernado por una ecuación constitutiva representativa del terreno. En ese artículo se presenta un modelo numérico, de anillos concéntricos, regidos por la ecuación constitutiva del Hardening Soil Model que pretende ser un marco de referencia para la interpretación del ensayo. El modelo analiza variables como son: los modos de respuesta, el estado inicial, el régimen de drenaje, y las ecuaciones constitutivas, pudiendo ser aplicado a cualquier formación geológica de la que se disponga de un número representativo de ensayos.
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.
