|GFA2D performs a global failure analysis for 2D geotechnical problems based on the stress output from a finite element analysis using a weighted method (WFEM). The local safety factors of soil elements are calculated based on the Mohr shear failure assumption. The failure surface is located throughout the defined searching zone. The global safety factor is defined as the weighted sum of local element safety factors for those elements on the possible failure surface. The input data file is similar to those for regular FEM software, except for eight more points to define a searching zone. The output data includes: stress, strain, failure surface and global safety factor. The advantages of this method: based on FEM output, the stress and strain results are more accurate, compared to those from sliced analysis: soil non-linear properties can be considered: soil-structure interaction effects can be considered. Works for slope, piled slope, foundations on slope, shallow foundations, and seismic earth dams.
