Dams due to their advantages such as the use of natural materials and relatively simple procedure, and lower cost, have always been considered. One of the important issues in the design and construction of earth dams is stability analysis of slopes that use in earth dams. There are various methods to slope stability analysis that one of the most important methods is Limit Equilibrium Method (LEM). By consideration that soil is a heterogeneous material; the analysis must be conducted in a manner that all of the plausible values be considered. By using statistical methods, we can evaluate the influence of soil parameters uncertainty in stability analysis of earth dam's slopes. One of the most applicable and important statistical method in engineering is MonteCalro simulation (MCs). In this paper we tried to evaluate the Influence of soil parameters uncertainty in earth dams slope stability by using limit equilibrium method of slices.
