土壤强固剂是一种新型的加固土体复合材料。文中通过室内击实、直剪以及无侧限抗压强度对比试验 ,分析了一种新型土壤强固剂对云南红土的加固效果。试验结果表明 :这种新型土壤强固剂对红土样的最大干密度基本无影响 ,但可提高红土样的最优含水量 ,特别是抗剪强度和无侧限抗压强度都有显著提高 ,强度加固效果系数都大于 1,变形加固效果系数都小于 1,其加固效果优于粉煤灰。证明这种新型土壤强固剂能够显著改善土体性能 ,减小变形 ,提高土体的承载能力。
Soil reinforcement is a new type of reinforced soil composite. Through the comparisons of indoor compaction, direct shear and unconfined compressive strength, this paper analyzes the reinforcement effect of a new type of soil strengthening agent on Yunnan laterite. The experimental results show that the new soil-based soil consolidating agent has little effect on the maximum dry density of red soil samples, but can improve the optimal water content of red soil-like samples, especially both the shear strength and the unconfined compressive strength , The strength reinforcement effect coefficient is greater than 1, deformation and reinforcement effect coefficient is less than 1, the reinforcement effect is better than fly ash. It is proved that this new soil solidifying agent can significantly improve the soil properties, reduce the deformation and improve the bearing capacity of the soil.
