Abstract: The strength reduction FEM (SRFEM) is the most popular method in geotechnical limit analysis FEM. It has been studied and applied in recent years quickly; and significant achievements have been obtained and its feasibility, superiority and practicability in geotechnical engineering have been proved. Several problems about SRFEM are discussed such as the definition of safety factor, utility condition of Mohr-Coulomb criterion and access to calculation parameters after the adequate praise and affirmation of its advantage and characteristics. It is concluded that the application conditions and access to calculation parameters of SRFEM should be carefully considered; the further and probable research might be turned to the safety and stability analysis of geotechnical structure with the emphasis on deformation control; and the development of professional calculation software of multiple methods and functions with the combination & complementation of traditional limit equilibrium method.

Key words: geotechnical engineering, strength reduction FEM, safety factor, Mohr-Coulomb criterion, shear failure
