| This paper presents the results of numerical investigation on the stability of reinforced earth wall during rainfall. A series of limit-equilibrium based slope stability analyses within the framework of unsaturated shear strength, coupled with transient seepage analyses, were conducted with due consideration of rainfall characteristics in Korea. It is shown that the factor of safety of the reinforced wall during rainfall decreases with time due to decreases in the suction in the reinforced as well as retained zones. Also revealed is that the decrease in the factor of safety depends not only on the backfill soil type but also on the rainfall characteristics. Practical implications of the findings were discussed. |
