Solidifying saline soil in inshore with different quantities of salt using lime
which causes the microstructure indices and strength of saline soil change obviously and increase greatly. It has been proved that strength has good correlation with microstructure indices with the help of multivariate stepwise regression method; and the five indices
including particle granularity fractal
particle orientation fractal
particle diameter
particle oblate degree
and particle area ratio
are the significant indices effected on the strength of solidified saline soil in inshore with lime. According to calculation results of microstructure indices
its fractal
and strength
solidifying mechanism of lime-saline soil can be certified from another aspect.
