  • Salty soil distributed widely and the engineering characteristic was complicated. The mechanical property had the relationship with spatial arrangement of soil grains, mineral component and occurrence condition of diffluent salt. The soil microstructure was an important factor to engineering characteristics. The influence of diffluent salt recrystallization on soil strength was learned according to the microstructure analysis by using environment scanning electron microscope and additional equipment X-ray energy spectrum (EDX). The influence of microstructure variation on salt soil strength was obtained by direct shear test on the salty soil before and after dehydrating. The results showed that diffluent salt recrystallization affected soil internal structure. The salty soil microstructure character was different before and after dehydrating, which changed the soilmechanical property of salty soil. © (2012) Trans Tech Publications, Switzerland.
