Abstract
The crack is generated in the soil structure by drying shrinkage, earthquake, creep deformation. In recent years, the observed rain intensity is greater than the past. However, it is not clear about the influence of the crack which provides the water level rises and rainfall infiltration into the soil structure. In this paper, the effect of crack on the model embankment was examined under rainfall. The tests showed that: as the number of cracks increase, the volumetric water content and the water level in the embankment increases. Furthermore, the water level per unit time is decreased with the repetition of rainfall. As one of the causes, we suggested the effect of adhesion of the crack.
