摘　　要：通过室内塑性指数、粘粒含量、pH值、有机质含量、颗粒组成不同的 5种土石灰稳定强度试验 ,分析土的这些特征指标对石灰土强度的影响 ;通过室内二灰土的正交试验 ,分析土的塑性指数、二灰含量、二灰比对二灰土强度的影响。其研究结论对石灰、二灰稳定土的组成设计和不良路用土的改性具有重要指导意义。Through indoor strength test of lime soil about five kinds of soil with different plastic index,content of sticky grain, pH,organic, graded,the authors analyze the influence factors on strength of lime soil caused by the characteristic index of soil.Through indoor orthogonal test,the effects of plastic index of soil,content of lime?ash, and proportion of lime?ash on the strength of lime?ash soil have been analyzed.The findings are important and instructive for component design of lime soil and lime?ash soil and the modification and stabilization of poor soil used for highway building.
