Research Abstract

This study is the study for the purpose of revealing the mechanism of seepage failure occurring at the boundary between the ground and irrigation facilities such as concrete embankments and headworks. The results of this study indicated that the previous seepage failure assessment methods are not possible to assess the effect of particle size of the soil around the irrigation facilities. We proposed a new assessment method that can evaluate the effect of particle size. We conducted the model tests that seepage failure occur at the ground with the movement of the irrigation facilities. This model tests indicated that it is necessary to consider the seepage as well as water pressure in the safety of the irrigation facilities. In addition, we have developed an analysis method that can be expressed at the same time the seepage failure of ground and movement of irrigation facilities.
