摘　　要：结合子洲～靖边高速公路4个合同段低液限粉土的情况，分别采用试验和理论分析的方法，对该地区广泛存在的低液限粉土底基层稳定性能进行了系统研究。首先对低液限粉土稳定土进行了物理、力学性质试验，取得了基本的研究参数。然后通过分析当前常用的路面底基层稳定土方案，对该地区的低液限粉土提出了稳定加固方案，并分析了加固机理和影响因素。On the basis of the low liquid limit silt got from 4 contract sections of Zi-Jing Expressway, the stability of the sub-base are systematicly studied by indoor experiments and theoretical analysis. Firstly, the experiments in laboratory are clone in order to get the basic physical and technical parameters of the low liquid limit silt. Then, the stabilization and consolidated scheme of the low liquid limit silt is put forward and the consolidated mechanism and influencing factors are analyzed through researching the stabilization method commonly used for sub-base in the district.
