Abstract
The paper describes a series of reliability analyses that were carried out to investigate the effect of statistical property of soil and reinforcement on reinforced soil structures. Statistical analyses were carried out to determine the probability distribution of the tensile strength of reinforcement. Limit state exceedance probabilities of reinforced slopes and retaining walls were obtained from the first-order and second moment (FOSM) method. Results of reliability analyses conducted with different average and coefficient of variation (COV) of soil and reinforcement parameters showed that the tensile strength of reinforcement can be assumed as a constant under the condition with a lower COV value. The effect of probability distribution of tensile strength of reinforcement is insignificant on reinforced soil slopes, while it is significant under the condition with a higher COV value on reinforced retaining walls.
