本文在论述国内外对生石灰、粉煤灰加固土研究成果的基础上,通过理论分析与试验研究,对生石灰—粉煤灰加固土的物理—力学性能、化学性质及微观结构性质进行了较为全面深入的研究,并将其与生石灰加固土、熟石灰加固土及熟石灰—粉煤灰加固土做了部分对比分析,提出了生石灰—粉煤灰加固土强度原理的几点结论。 Based on the domestic and international research results on quicklime and flyash reinforced soil, this paper makes a comprehensive analysis of the physical-mechanical properties, chemical properties and microstructure of quicklime-flyash reinforced soil by theoretical analysis and experimental study In-depth study and comparison with the quicklime reinforced soil, slaked lime stabilized soil and slaked lime-fly ash reinforced soil, and some conclusions about the strength principle of quicklime-flyash reinforced soil are put forward.
