A study on the limit state design method for retaining wall structures are reviewed based on the National Retaining wall Design Standard. In this paper several retaining walls are calculated according to LRFD design criteria analysis using the program and the factor of safety for sliding and overturning. Comparing with their results, the Taylor's series simple reliability analysis was performed. In the futures more study should needed including reinforced retaining walls, earth anchor structures. Geotechnical data also are evaluated beforehand.
