Abstract: Slope stability evaluation has an important role in the geologic hazards prevention and minimization. This paper evaluates a highway slope by using the finite element analysis (FEA) with strength reduction method. The relationship between the stability number and the deformation failure is developed through the analyses. The FEA results are also compared with the results from the limit equilibrium method. It is concluded that the FEA with strength reduction can better represent the stress distributions within the slope.
