Reliability analysis for static stability of reinforced soil

Retaining walls are walls that maintain the pressure caused by the existing state of the difference in levels caused by embankment, excavation or natural factors. In this study the stability of the flexible walls and the type of reinforced soil walls are evaluated to examine the stability and design the retaining walls with reliability method which gives more realistic results than other design methods. Reinforced soil wall is a special material that is formed by the combination of the soil and the reinforcement member. Basically the soil is weak in stretching and cutting and the idea of reinforced soil wall is in fact the solution to this problem. There are many uncertainties in civil engineering and in particular in the geotechnical discussions the discussion of the uncertainty of the parameters is much more evident because the anonymity of the soil behavior. The traditional methods of evaluated the stability of reinforced soil walls which are usually based on empirical judgments such as the concept of a coefficient. Efforts to quantify uncertainties causing genesis of probabilistic methods. Probabilistic analysis in comparison with definite analysis the uncertainties in the calculations and instead of using the confidence coefficient in the project safety level it usually uses the probability of failure or the reliability index
