| Abstract: | 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 done 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. |
