ANALYSIS ABOUT THE FACTORS INFLUENCE THE STRENGTH OF FINE GRAINED SOIL STABILITIED BY LIME AND LIME-ASH

Through an indoor strength test of lime soil with five kinds of soil with a different plastic index, the content of sticky grain, pH, organic, and graded, this paper analyzed the influencing factors on the strength of lime soil caused by the characteristic index of soil. Through an indoor orthogonal test, the effects of the plastic index of soil, content of lime-ash, and proportion of lime-ash on the strength of lime-ash soil have been analyzed. The findings are important and instructive for the component design of lime soil and lime-ash soil and the modification and stabilization of poor soil used for highway building.
