Effect of Intermediate Principal-Stress Ratio on Particle Breakage of Rockfill Material
Publication: Journal of Geotechnical and Geoenvironmental Engineering
Volume 142, Issue 4
Abstract
The true triaxial compression test is the three-dimensional test, where the intermediate principal stress is not less than the minor principal stress and not more than the major principal stress. The effect of the intermediate principal stress ratio (i.e., the -value) on particle breakage of rockfill material (RFM) was investigated by conducting a series of true triaxial compression tests under the constant- and constant- loading condition. It was observed that the relative breakage extent of RFM increased with an increase in confining pressure but decreased with an increase in -value. The effect of the -value on the particle breakage of RFM was well predicted by an empirical equation.
