This paper analyzes the impact of the weak interlayer on the 3D slope stability and failure mode.Example of a classic 3D slope is calculated and the results were compared with the limit equilibrium method toverify the reliability of strength reduction elastoplastic finite element method. And then an example of a 3Dglope with weak interlayer is analyzed, the results show that; the ellipsoid failure surface in the longitudinallength calculated by strength reduction elastoplastic finite element method is larger than the limit equilibriummethod; compared with the 3D homogeneous slope, the factor safety of 3D slope with weak interlayer is muchlower, the scope of failure surface is much larger, the phenomenon of the concentration of plastic strain zone ismore obvious, and the failure mode has many signifcant differences.
