Resumo

El artículo muestra una revisión bibliográfi ca de los principales modelos que existen para el cálculo de la dilatancia en la roca. una vez explicado cada modelo, se procede a realizar el modelamiento matemático de ésta propiedad.

Esto se realiza mediante datos suministrados por la literatura, las cuales son: esfuerzos sometidos a la roca σ1,σ2,σ3, ángulo de fricción interna ∅, pendiente de la línea de estado critico M, el parámetro de estado , y otras constantes que se requieren para cada modelo. Una vez hechos los cálculos de la dilatancia en la roca, se procede a validar el modelamiento con datos reales, los cuales también son suministrados por la literatura. En éstas pruebas se midió la dilatancia real en dos tipos de arena, (Banding y Miga) y se realizaron 5 pruebas. Finalmente éstas mediciones se compararon con los cálculos realizados, y así llegar a la conclusión de que el mejor modelo para predecir el fenómeno dilatante de una roca es el de Li & Dafalias.
