Simulating the particle size distribution of rockfill materials based on its statistical regularity

1. Introduction Rockfill has excellent engineering characteristics, such as good compactness, better seepage ability, high density, low sedimentation, high shear strength and so on. So it is widely used in dams, bed of railway and deep foundations[1-2]. Two types of rockfill are commonly used in constructions, that is inartificial rockfill such as gravel and scree, and blasted rockfill, e.g. fragmental stone, macadam and moraine soil.
