Earthquake geotechnical engineering has developed enormously in the last decades. This article focuses on the seismic design of geosynthetic-reinforced soil structures. It presents the available calculation methods. Pseudo-static and pseudo-dynamic approaches based on the limit state analysis are compared. Their advantages and disadvantages are discussed. This article also presents the results of external stability analysis for a waterfront reinforced soil retaining structure subjected to seismic forces. The results were obtained by a selected pseudo-static method of calculations. Parametric studies were carried out to quantify the effect of different factors, such as the angle of internal friction and the magnitude of seismic accelerations, on the minimum length of the geosynthetic reinforcement required to ensure the seismic stability of reinforced soil structures. Main practical conclusions are described.
