Study on Grain Breakage in Triaxial Test of Rockfill Material

Abstract:

Article Preview

Large-scale triaxial test has been conducted on various rockfill materials in an attempt to study the degrees of grain breakage. The result has shown that, the grain breakage occurred during sample preparation can not be neglected, and to maintain the initial gradation design prior to consolidation, the gradation design shall be adjusted downwards to a certain extent accordingly before sample preparation. The breakage of large-sized grains mainly occurs on the surface, and the grain breakage and confining pressure has shown linear relations after triaxial test.
