%X 建立基于指标满意度的多指标正交试验综合评价模型，选取质量浓度、灰砂比、粉煤灰掺量、减水剂掺量等4个因素，进行4因素3水平的正交试验，选取充填体28 d单轴抗压强度、28 d抗拉强度、塌落度、成本等4个指标进行基于指标满意度的多指标综合评价及敏感性分析. 试验结果表明： 质量浓度、灰砂比、粉煤灰掺量、减水剂掺量对充填体质量的敏感度分别为0.217、0.252、0.032和0.060，即灰砂比对充填体质量的影响最大；质量浓度对充填体质量有着明显的影响；粉煤灰掺量及减水剂掺量对充填体质量的影响相对较小.<br>Comprehensive evaluation modal of multi-index orthogonal test based on satisfaction indicators is established. Four factors(mass concentration，cement-sand ratio，fly ash dosage and superplasticizer dosage) and three levels were chosen to conduct the orthogonal test. The model of multi-index comprehensive evaluation and sensibility analysis was carried out with four indexes selected: 28 d uniaxial compressive strength，28 d tensile strength，collapsed slump and cost. Results show that the sensitivity of four factors are 0.217，0.252，0.032 and 0.060，respectively. Cement-sand ratio is the most sensitive factor which influence backfill quality，mass concentration has an obvious effect on backfill quality，while the fly dosage and superplasticizer dosage have less impact on it
