摘　　要：为了研究在单轴条件下矸石粉煤灰充填材料的压实特性,分别针对不同粒径的矸石以及不同配比的矸石粉煤灰进行实验研究。通过多次对比实验和理论分析,得到了矸石和矸石粉煤灰在单轴压缩情况下的压实特性、抗变形能力、矸石粉煤灰的最佳配比方案,为今后人们更加深入研究充填体的变形特征与充填体的级配选择提供理论依据。To study the compaction characteristics with waste and ash under the condition of uniaxial compaction, the experimental study is carried out on the gangue with different sizes and different ratio of with waste and ash. Through many times comparative experiments and theoretical analysis, the compaction property, anti deformation ability and the best ratio with of waste and ash under uniaxial compression are obtained. It provides theoretical basis for further study of the deformation characteristics and gradation selection of filling body.
