On the Application of Finite Element Method (FEM) to the Slope Stability Analyses

The finite element method (FEM) is widely adopted in the geotechnical engineering, but there exist some problems in practical applications, such as the lack of unified standard to determine parameters and the limitation of the calculation method. This article determines the reasonable value of Poisson ratio, by comparing different Poisson ratios selected in the strength reduction of FEM calculations, and improves the gravity increase method in order to enhance its accuracy in the gentle slope stability analyses.
