Frontiers of Structural and Civil Engineering 2007, Volume 1, Issue 2,   Pages 198-204 doi: 10.1007/s11709-007-0023-1

Abstract: The intensive soil-water interaction in unsaturated expansive soil is one of the major reasons for slopeIn this paper, the soil-water interaction is investigated with the full-scale field inspection of rainwaterIt is demonstrated that the soil-water interaction induced by seasonal wetting-drying cycles is verycomplex, and it involves coupled effects among the changes in water content, suction, stress, deformationIn addition, the abundant cracks in the expansive soil play an important role in the soil-water interaction
