A lot of geotextile reinforced soils are designed, and constructed in Japan where the earthquake happens frequently. Therefore, the stability of the geotextile reinforcement soil at the earthquake is also very important. In general, the creep decrease of reinforcement is considered in the design of the ordinary condition. On the other hand, allowable strength of reinforcement is surcharged in the design at the earthquake. In this research, the test series were carried out to investigate the residual strength and creep performance of geogrid that is made from the continuous fiber of polyester. This paper describes the validity of the allowable strength of geogrid and proposes the extra coefficient of allowable strength of geogrid for seismic design.
