A twodimensional plane-strain numerical model has been developed to simulate steep nailed slopes by finite element software, MIDAS GTS. The real time-history analyses are carried out to study the seismic response of nailed-soil slopes. The effect of various influencing parameters such as the nail inclinations and the slope angles on the seismic resistance and failure mechanism of the nailed slopes are studied in details. The numerical model developed has been used to examine the shaking table test results of steep nailed slopes [1]. The nailed soil slopes are modeled in FE analysis as per the geometry of shake table testing and the numerical analysis are carried out for different seismic excitations. The numerical results such as maximum lateral displacements at various heights of the facing are compared with the test results for various slopes angles, nail inclinations and peak amplitude of accelerations. The failure pattern of nailed soil slopes for different seismic conditions obtained from the numerical analysis are studied and compared with the experimental failure patterns. A reasonable agreement between the finite element analysis and shaking table test results are obtained.
