A reliability analysis of 640m long retaining wall for an embedded highway has been carried out. The soil profile at the site mainly consists of alternation of three cohesive and cohesionless soil layers. The soil investigations have been conducted by the borings (SPT N-values) of about 100 m interval. It was found that the most dominant source of uncertainty to control the performance of the retaining wall is the thickness of the soil layers which are different from a section to another. The layers ‘hicknesses are modeled as correlated random processes whose thicknesses are known at the location of the borings. The thickness of a layer at a certain location is estimated by co-Kriging method and the conditional simulation based on it with quantified uncertainty.
