Control soil salt expansion dynamics of the basic elements of earth, water, salt, temperature , force . Based on 12 Kashi basic properties of natural indoor saline soil test analysis, select a typical natural saline soil under conditions of repeated freeze-thaw cycles of the pilot study results of three typical natural saline soil has experienced repeated freezing and thawing when salt expansion rule , salt inflation rate and the relationship cycle . Meanwhile, for the three typical experience different natural saline soil in freeze-thaw cycles , were carried out water, salt migration test and shear strength tests , obtained three typical natural saline soil in the process of freeze-thaw cycles water, salt and salt expansion after the migration of the layers of soil mechanical strength variation , further revealed accumulation of salt expansion mechanism and influencing factors, Kashi road saline soil disease control provides practical technical parameters values ??.
