【Abstract】： Inorder to clarify the influence of temperatureonthedrainage consolidation characteristics of alkali slag，a GDS temperature controled advanced consolidation instrument was used to conduct aone-dimensional thermal consolidation permeability joint test on Tianjin alkali slag.The consolidation characteristics of alkali slag under diferent temperatures，consolidation pressures，and stepwise heating conditions were analyzed.The test results show that：in the range of 20～80 ∘C ，the permeability and compression of alkali slag increase with the increase of temperature；in the process of step-by-step temperature increase，the increase of temperature produces a positive excess pore water pressure in alkali slag，and the compression of alkali slag increases with the dissipation of pore pressure.
