针对高液限粘土稳定性差的性质，添加各种外掺剂，研究其混合土料的强度变化规律．采用室内试验分析比较、技术经济指标筛选和试验路段检验的综合分析方法，确定了外掺剂类型和实用的工程配比．研究结果认为，在高液限粘土中掺入4％的石灰所形成的石灰稳定土，达到了实际工程要求．并取得良好的经济效果．
Aiming at the poor stability of high liquid limit clay, various additives were added to study the variation of strength of mixed clay. Through the analysis and comparison of indoor test, technical and economic index screening and comprehensive analysis of test sections, the types of external admixture and practical engineering proportion were determined. The results show that the lime-stabilized soil formed by blending 4% lime in high liquid-limit clay meets the actual engineering requirements. And achieved good economic results.
