英文摘要	Salt expansion was the main diseases of the salty foundation. In order to study the deformation regularity and quantitative description of coarse particles saline soil ground in natural condition, a field test was conducted in Dunhuang area. The exploratory well with 7.5 m depth (deeper then annual temperature change layer) was excavated on site, and the data of salt content \water content\ground temperature\salt expansion rate were collected. From the test it was found that : salt expansion mainly decided by salt content, salt content and salt expansion rate have approximately a quadratic function relationship; the minimum salt content could cause soil expansion is 1.5%; The salt expansion force was strong, and the gravitational stress could not suppress the deformation.
