Abstract:

Solidifying inshore saline soil with lime, which causes the microstructure indices of saline soil change obviously because of a lot of chloride. With the help of Leica QWin5000 software it has been proved that microstructure indices, including particle diameter, particle oblate degree, and particle area ratio, increase or decrease at approximately linear relationship with the increase of salt content through analyzing SEM’s photos. With the increase of salt content fractal dimension of particle granularity has been increased; and uniformity degree of particles diameter has been decreased; however fractal dimension of particle orientation rises firstly; secondly decreases, and finally is stable progressively; and orientation of particle is fixed in the some direction. And the conclusion is corresponding with the results of particle size analysis of solidified soil.

Key words: inshore saline soil, salt content, microstructure, fractal dimension, solidified saline soil with lime
