摘　　要：通过EDTA滴定试验,建立了不同养护条件和压实状态下有效钙镁含量的数学模型,分析研究应用于道路工程的石灰稳定废弃泥浆的有效钙镁含量的衰减规律。研究结果表明:石灰稳定废弃泥浆的有效钙镁含量与石灰掺量呈线性关系,有效钙镁含量的衰减模型与养护条件和压实状态有关。通过模型数据和试验数据对比发现,建立有效钙镁含量衰减模型具有一定的预测精度。Through EDTA titration test,the mathematical model of effective calcium and magnesium content under different curing conditions and compaction state is established.The attenuation law of effect calcium and magnesium content in the lime stabilized waste slurry applied to road engineering is analyzed and studied.The results of the research show that there is a linear relationship between the effective calcium and magnesium content of lime stabilized waste slurry and lime dosage,and the attenuation model of effective calcium and magnesium content is related to curing conditions and compaction state.Through the comparison of model data and experimental data,it is found that the established attenuation model of effective calcium and magnesium content has a certain prediction accuracy.
