A Study of the Rockfill Material Behavior in Large-Scale Tests [PDF]
Civil Engineering Infrastructures Journal, 2013 Inspecting the behavior of the rockfill materials is of significant importance in analysis of rockfill dams. Since the dimensions of grains in such materials are greater than the conventional sizes suitable for soil mechanics tests, it is necessary to ...
