| Research Abstract |
This study has challenged to reveal the mechanism of embankment failure owing to overflow, as well as piping phenomenon, and to predict the damage of the earth structures for irrigation and flood prevention. The study has proposed the analyzing scheme of the temporal development of piping, has theoretically and experimentally showed the failure mechanism of embankments due to overflow, and has enabled the time required for the failure to be predicted. These results are now combined with risk analysis, which leads to the functional assessment of the soil structures.
