摘　　要：SRR土壤固化剂是一种新型土壤加固材料,本文基于对湖南省衡阳市锰矿矿渣土壤和株洲市黏性黄土土壤进行最佳含水率测试后,对比分析SSR土壤固化剂对土壤抗压强度的影响。筛选10 mm以下粒径土壤作为无侧限抗压强度标准小试件,在3%生石灰、5%的水泥、100 ml/m3 SRR土壤固化剂等不同材料的配合下,进行无侧限抗压强度对比试验研究。结果表明:SRR固化剂能减少锰渣土的吸水量,从而提高土壤自身强度,且提升幅度远高于水泥及生石灰;对于株洲黏性黄土,抗压强度的提升较小,但其强化效果仍强于水泥及生石灰。SRR soil curing agent is a new type of soil reinforcement material. In this paper, we compare and analyze the effect of SSR soil curing agent on the compressive strength of soil based on the optimal moisture content test of manganese mine slag soil in Hengyang City, Hunan Province and clay loess soil in Zhuzhou City. Soil with particle size below 10mm was selected as the standard small specimen of unconfined compressive strength, and a comparative test study of unconfined compressive strength was conducted with different materials such as 3% quicklime, 5% cement and 100 ml/m3 SRR soil curing agent. The results show that SRR curing agent improves the soil’s own strength by reducing the water absorption of manganese residue soil, and the improvement is much higher than that of cement and quicklime;for Zhuzhou clay loess, the improvement of compressive strength is smaller, but the strengthening effect is still stronger than that of cement and quicklime.
