Abstract
In recent years, railway embankments often collapsed due to severe rainfall in Japan. It is well known that the stability of the embankments decreases if the water level or the degree of saturation increases after rainfall. However, the characteristics of the accumulated settlement after the occurrence of severe rainfall has not been studied clearly. In this study, the cyclic triaxial tests using existing embankment materials were performed to study the influence of the kind of materials or the loading conditions on the characteristics of accumulated settlement. Furthermore, the influence of the change of the water content during cyclic loading was studied in order to evaluate the influence of rainfall on the characteristic of the accumulated strain.
