In this study, numerical analyses and model tests were conducted to figure out the behavior of a slope reinforced by upward drainable soil nails during rainfall. The model tests were carried out on both reinforced and unreinforced slopes. To verify the results of the tests, seepage analyses were performed and compared with the test results using a commercial program, SEEP/W. The results showed that the numerical analyses have in overall a good agreement with the experiments in the variations of ground water level and pore water pressure even though there is some time delay for the experiment before the changes in the ground water level and pore water pressure after rainfall are observed, while the numerical analyses not.
