中文摘要：
天然堆石料的颗粒破碎率不易准确测量。为精确测量堆石料的颗粒破碎率,对人工模拟堆石料进行了颗粒破碎三轴试验研究,并对试验后试样颗粒破碎的情况进行了详细筛分和统计。结果表明：破碎颗粒可分为残缺颗粒和完全破碎颗粒,两者的质量分数存在幂函数关系。现有的多粒径指标Bg、Bf和Br仍可作为颗粒破碎的影响参量使用,而单一粒径破碎指标B15、B10和B60局限性较大。
英文摘要：
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, Bg, Bf, and Br, based on the grain-size distribution curve can be used as a particle breakage parameter, but the single grain indices, B15, B10, and B60, have severe limitations.
