Parametric Study on Earthquake-Induced Slope Deformations
A parametric study is conducted to evaluate the effects of complex soil behaviors on earthquake-induced slope deformations. A validated two-dimensional Smoothed Particle Hydrodynamics (SPH) model is utilized in this numerical study. This SPH model fully accounts for the effects of nonlinear soil behavior during cyclic loading, strain hardening/softening during sliding, strain-rate dependent shear strength, and dynamic response of the slope and sliding mass. Results of this parametric study demonstrate the importance of strain-rate dependent shear strength and post-peak strain softening on the initiation of earthquake-induced slope movement and subsequent progressive slope deformations. Hence it is concluded that these effects should be considered in evaluating the seismic performance of natural and man-made slopes.
