摘　　要：对安庆铜矿特大型采场不同配比的充填体进行了无侧限单轴抗压强度试验，根据试验测得的充填体应力～应变曲线，建立了充填体的损伤演化方程，并对其损伤本构关系进行了分析研究。The unconfined uniaxial compression strength tests of backfill, at a different ratio of fill, in the special large-sized slope in An＇qing copper mine were made. According to the measured full stress-strain curve of backfill, the equation of damage evolution of backfill was formulated and the constitutive relation of damage was analyzed.
