Investigation of the Rockfill Materials Properties Based on the Confining Pressure Effect and the Rock Type

Rockfill materials have been widely utilized in large structures as well as rockfill breakwaters and rockfill dams construction. Design procedure of such structures requires a rather precise estimation of geomechanical properties of such materials and hence, such properties are often evaluated with great difficulty. In this research, one of the important parameters commonly used in elasto-plastic constitutive model, namely dilationangle, is investigated by studying triaxial test results on five rockfill materials.
