Abstract

The dissolve settlement characteristics of sulphate saline soil were analyzed by centrifugal simulation test. The results show that the coefficients of dissolve settlement increase with the increase of centrifugal acceleration and are not relevant to salt content. The coefficients of dissolve settlement are very sensitive when the centrifugal force is less than 300 kPa. Its dissolve settlement deformation is the greatest when the content of SO42- is 2.14%.
