Outline of Final Research Achievements

In this research, the risk evaluation system has been developed for the maintenance of the agricultural infrastructures such as dams, other irrigation facilities and polder dikes against the severe earthquakes and the heavy rains. The concrete outcomes are as follows. 1) The model test system has been developed to study the liquefaction behavior of the embankment structures, and the mechanism of the liquefaction inside the structures has been clarified. 2) The analytical tools to evaluate the stability against the earthquakes, and the heavy rains, and evaluate the dam breaches and floods, have been developed. 3) The sounding tests and the physical exploration tests have been proposed and their effectiveness has been verified by applying the tests to the in-situ problems. 4) The total risk evaluation system for the optimum maintenance of the agricultural infrastructures has been proposed.
