Abstract
Rainfall would reduce the seismic resistance of an embankment if the drainage system of the embankment is not enough; however, aseismic design of embankments does not consider this effect. Based on the seismic response calculation results using a FEM code ‘FLIP’ and the previous shaking table test results, the effect of rainfall on seismic performance of embankments was examined in this study. As a conclusion, the reduction of the soil cohesion of embankment by the seepage due to rainfall is very important.
