Reduction factor by creep deformation test of geogrids was interpreted to determine the long-term design strength. For this, limit creep strain of geogrids was analyzed to consider the material strain property. Limit creep strain of geogrids in this study was not over $10\%$ during 10000 hours. Sherby-Dorn plots were applied to compare the real limit strain criteria (GRI Test Method GG-4). Through Sherby-Dorn plots of creep deformation behaviors of geogrids. It was seen that the limit creep strain was $11\%$. This value is higher than the existing criteria of $10\%$. From this limit creep strain 11$\%$, reduction factor from the creep deformation test was 1.45 during 10,000 hours for geogrids. Finally, creep reduction factors of $10\%\;and\;11\%$ limit creep strains were compared and analyzed to interpretate the difference of reduction factor $0.06\~0.14.$

크리프 시험결과 해석을 통하여 한계 크리프 변형률 개념에 의한 크리프 감소인자를 평가하는 새로운 절차를 소개하였다. 지오그리드의 한계 크리프 변형률을 결정하기 위하여, Sherby-Dorm Plots을 적용하였으며 그 결과를 각각 비교, 해석하였다. 이로부터 본 연구에 사용된 지오그리드 시료들의 크리프 감소인자는 1.45임을 알 수 있었다. 10% 임계 크리프 변형률에서의 크리프 감소인자 비교를 통하여 본 연구에 사용된 지오그리드 시료들의 크리프 감소인자의 감소폭은 약 0.06~0.14 범위임을 확인할 수 있었다. New procedure for evaluation of creep reduction factor by the limit creep strain concept was introduced through the analysis of creep test results. To determine the limit creep strain of the geogrids, the Sherby-Dorm Plots were applied and the results of this procedure were compared and interpreted, respectively. From this, it is seen that the creep reduction factors were 1.45 for the geogrid samples used in this study. Through the comparison of creep reduction factors in 10% creep strain criteria, it was confirmed that the range of creep reduction factor is about 0.06 0.14 for the geogrid samples in this study.
