Abstract
In this paper, the stability of a real case MSE wall was analyzed using a finite difference numerical analysis program and a limit equilibrium slope stability program. It was found that the two programs determined similar factors of safety for the wall, but different critical failure surfaces. Such a discrepancy was due to the different underlying assumptions associated with the two analysis techniques. Considering the complexity of many real-world projects, it is recommended that two or more independent analyses using different techniques should be considered in order to obtain a better evaluation of the wall stability.
