摘　　要：为综合利用铁尾矿废渣和工业粉煤灰,通过掺加不同剂量的水泥和粉煤灰处治铁尾矿渣用作半刚性路面基层,对5个级配的混合料进行抗冲刷性预测分析。结果表明:铁尾矿砂属于细集料,为了提高混合料的密实性,应掺入粉煤灰,随着水泥剂量由3%逐步提高至7%,冲刷量下降很明显,当水泥掺加计量为7%时满足抗冲刷要求。In order to comprehensively utilize iron tailing waste slag and industrial fly ash,the iron tailings slag was treated as a semi-rigid pavement base by adding different doses of cement and fly ash to predict and analyze the erosion resistance of the five graded mixtures.The results show:iron tailings slag is a fine aggregate.In order to improve the compactness of the mixture,fly ash should be added.As the cement dosage gradually increases from 3%to 7%,the erosion amount decreases significantly;when the cement dosage is at 7%,it meets the anti-scour requirements.
