Dynamic response of loess slope with uniform and isotropic layers to vertically incident strong shear waves with different vibrating directions
Dynamic responses of a loess slope with uniform and isotropic layers to vertically incident shear waves with different vibrating directions are analyzed in this paper by numerical simulat ing method.The dynamic responses (distribution patterns of maximum displacement and plastic zones) of Changshougou loess slope to the excitation of vertically incident shear waves with different vibrat ing directions are simulated by the FLAC3D software.The simulating results indicate that the dynamic responses of the slope to vertically incident shear waves with different vibrating directions are almost the same.The physical mechanism of the phenomena is revealed in the light of wave energy theory and seismic wave ray theory.The distribution patterns (the convergence and divergence) of wave energy in the slope are controlled by the propagating directions of waves, but not their vibrating directions The study results of this paper offer a foundation for probability analysis of earthquake-induced slope failures.
