A method is investigated to analyze the reliability of the gravity retaining wall which is designed to allow a limiting translational movement induces by the earthquake loading. Application of FOSM method to the Richards and Elms model yields a practical procedure for the analyses of the reliability and sensitivity of the retaining wall sujected to the earthquake. After examination of the practice (or the earthquake design of the retaining wall, the methods of the reliability analysis are considered. Finally, this study presents the step-by.step procedure for analyzing the reliability of the earth retaining structure for pratical convinience.
