Abstract: An elastoplastic strength reduction FEM is utilized in the analysis of slope stability and reinforcing; and the authors present a well-defined total equivalent plastic strain (TEPS) zone as the failure criterion when it running through the bottom to the top of a slope by the strength reduction FEM method. So, the conception of failure of a slope is clear. At the same time, the strength reduction coefficient before the TEPS zone is considered as the safety factor of a slope; thus, the sliding surface must be located at the zone of TEPS. The results of stability analysis and the reinforcing calculation of a certain slope in a certain water supply reconstruction project show that the TEPS zone as a failure criterion of strength reduction FEM is reasonable and can be widely applied to slope engineering practice.

Key words: slope, strength reduction method, elastoplastic FEM, stability coefficient, reinforcing analysis
