N2 - Heavy rainfall is considered to be the main cause of the slope failures that lead to collapse catastrophically without prior warning. Even in the geogrid reinforced soil structures, the possibility o f collapse caused by rainfall remains. The infiltration induced by rainfall might weaken the reinforced strength and the stability potential. In order to investigate the effect of rainfall on the stability of geogrid reinforced soil structures, this paper presents the results from a series of pullout tests investigating interface behavior between soil and geogrid paying attention to the rainfall infiltration.. It is shown that the water presence dominate the behaviors of soil-geogrid interface and soil mass around it. This study also provides a basis for further research the strength loss of reinforced soil structures induced by heavy rainfall.
