Seismic Stability Analysis of Slopes Using a Pseudo-Dynamic Method Combined with an Upper Bound Method
Pseudo-static methods are commonly employed to analyze slope stability in seismic design, but these methods neglect ground acceleration characteristics (i.e., frequency and duration). In this paper, a pseudo-dynamic method, combined with a kinematic limit analysis method, was developed to calculate the translational seismic stability of slopes with a weak layer, based on the two-part wedge failure mechanism. The proposed method was validated against results from different limit equilibrium methods. Parametric analyses were also conducted to investigate the effects of loading time, frequency, vertical acceleration, slope geometry, and soil strength on slope stabilities.
