| Abstract: | In light of the poor stability of low liquid limit silt,the stabilization of the Zi-jing Expressway sub-base of low liquid limit silt,is studied by laboratory experiments and theoretical analysis.Firstly,the experiments in laboratory are conducted to get the basic physico-mechanical parameters of the low liquid limit silt.Then,the stabilization and consolidation scheme of it and the principles and influencing factors of stabilization are analyzed.Finally,the best stabilization and consolidation scheme of low liquid limit silt is proposed;and the influence law of physical index for steady effect is given. |
