RESUMEN: En este estudio, el fracturamiento de gravas es evaluado usando ensayos the compresión unidireccional, por simulaciones numéricas, y por un analisis teórico. Las simulaciones numéricas usan el Metodo de Elementos Discretos (DEM). La teoría de los fractales fue usada pra interpretar los resultados de laboratorio. Los experimentos y las simulaciones numéricas indicaron que la grava bajo compresión desarrollo cadenas de fuerza entre las particulas. Estadas cadenas de fuerza resisten la fuerza de compresión inducida a la grava. Cuando la intensidad de las cadenas de fuerza excede la resistencia a la compresión de la grava, esta se quiebra. La distribución del tamaño de granos despues de la compresión resulta ser fractal.
