摘　　要：为有效利用堆积的铁尾矿,以铁尾矿、水泥、秸秆、p H值调节剂等配制植生基质喷播到裸露的岩质边坡。研究了水泥掺量、p H值调节剂剂量为影响因素配制的植生基质的无侧限抗压强度随着龄期的变化规律。通过对试验数据的分析可知,当水泥掺量为6%时,植生基质的强度可以满足工程要求;无侧限抗压强度随p H值调节剂剂量的增加而降低;植生基质加入6%的p H值调节剂和8%的水泥时,14d龄期时的抗压强度迅速增加。In order to make full use of the packed iron tailings, iron tailings, cement, straw and pH regulator were used to prepare planting material sprayed on the slope of the exposed rock. Based on the influencing factors of the cement content and pH regulator dosage, this research aims to study the change law of the unconfined compressive strength with the change of its age. The results showed that, when the cement content is 6%, the strength of planting material can meet the engineering requirement. With the pH regulator dosage increases, the unconfined compressive strength reduces. When 6% and 8% of pH regulator dosage and cement added into the planting material respectively, the unconfined compressive strength increases quickly in 14d.
