Popis: Lime treatment technique is a convenient and common method used to improve expansive clays in engineering properties. The soil-water characteristic curve (SWCC) plays a role on engineering features of unsaturated lime-treated expansive clays. Herein, the soil-water characteristic tests by means of GDS and simulations were conducted to investigate the SWCCs of lime-treated expansive clays in Hefei. The results show that lime-treated expansive soil behaves hysteretic characteristics. Under the same value of suction, the higher cell pressure the larger the volumetric water content is. The numerical simulations from Fredlund model do good agreement with tests.
