| Abstract: | The existing experimental study on swelling deformation of expansive soil is performed through the convilent apparatus and the portable consolidation apparatus.This paper studies the swelling deformationg of expansive soil and lime improving expansive soil by contrastive CBR tests,and the changing rule of swelling-quantity and time expanding-velocity has been gained,which is helpful to the engineering practice. |
