Abstract A new variational method treating the system as a whole with rigorous mathematical and physical derivation
was presented in this paper. Combined with classical and engineering examples, variational energy expressions
of slopes were derived. In addition, the calculation programs were written in the FISH language set in FLAC3D
(fast Lagrangian analysis of continua in three dimensions) software. Factors of safety (FOSs) of the models were
determined by the variational method based on the strength reduction method (SRM) and then compared with
other criteria or methods. The result showed that the variational method reflected the process of slope plasticity and
failure… More >
