This paper describes results of numerical analysis on pullout behavior of steel-strip reinforcement based on anchorage effect. The numerical analysis results is compared with pullout test results under same condition of soil and reinforcement. In the relationship between pullout force and front displacement, the analysis result differed from test’s due to strain softening model. Therefore, the interface model characteristic between soil and reinforcement should be considered in the pullout resistance using numerical analysis. However, the pullout procedure can be fully confirm based on numerical analysis.
