| Outline of Final Research Achievements |
In recent earthquakes, several damages were caused due to the occurrence of the liquefaction in the body of embankments. In these damages, the water level was often located in the body of embankment. However, the mechanism of the damages have not been clarified and the effective countermeasure methods have not been established. In this research, unsaturated cyclic loading tests of embankment materials were conducted and the numerical technique was developed, in order to establish the method for the evaluation of liquefaction of body of embankment. Furthermore, the effect of the countermeasure method and the influence of the water content before earthquake to the occurrence of the liquefaction were examined by use of the developed numerical technique.
