中文摘要	The particle breakage ratio of real rockfill materials is difficult to measure precisely. The accuracy was improved in triaxial tests of artificial rockfill materials with the particle breakage of the samples after the tests determined by sieving and statistical analysis. The tests show that the fragmentary particles and completely cracked particles can be distinguished after the particles are crushed and the relationship between their mass percentages can be fit by a power law function. The particle breakage indices, B/sub g/, B/sub f/, and B/sub r/, based on the grain-size distribution curve can be used as a particle breakage parameter, but the single grain indices, B/sub 15/, B/sub 10/, and B/sub 60/, have severe limitations.
