Abstract
The scope of the paper is to presente two general melhods to calculate Fs=γμ the factor of safety in relation to the Limit Equilibrium (EQU) of soil (and/or rock) masses. According to the Eurocode for Geotechnical Design (EC7), γμ is a reducing factor for the strength characteristics of the soils (cohesion c and tanφ, – φ=friction angle). The first is a generalized method of slices and the second is the "Rigid Blocks Method". Computer programs have been put forward to to calculate Fs= γμ not only for the stability of slopes, but also for problems such as shallow tunnels. Comparisons of results with those in published examples have been done. In conclusion it can be said that to get a safe answer for Fs= γμ in Engineering Practice, two or more mehords must be used and results must be compared.
