摘　　要：根据对回填砂石试验数据分析,发现砂石颗粒级配不合理会造成回填段不密实,从而产生卸载。通过对回填试验的砂石级配与土力学中的土颗粒级配进行理论分析,分别采用不同级配的砂石进行回填实验,比较各回填段的压缩量,研究砂石级配对回填密实度的影响,并根据土力学中的颗粒级配理论确定了回填段较密实的砂石级配。Based on the analysis of experimental data backfill gravel,sand particle size distribution that would result in unreasonable backfill section is not compact,resulting in unloading.By graded gravel backfill test in soil mechanics and soil particle size distribution of theoretical analysis,were used for different gradation of the gravel backfill experiments to compare the amount of compression of the backfill sections,gravel gradation of the density of the backfill and,based on soil mechanics theory to determine the particle size distribution than the dense sand and gravel backfill section grading.
