Seismic response analysis of slope sites exposed to obliquely incident P waves

This study proposes a seismic input method for layered slope sites exposed to obliquely-incident waves which transforms the into equivalent nodal forces that act on truncated boundary of finite element model. The at left and right boundaries are obtained by combining free field response one-dimensional model with viscoelastic boundary. bottom incident wave proposed obliquely is implemented aid MATLAB software; it applied analysis in commercial ABAQUS software. calculation results compared reference solutions using extended verify correctness established method. then employed investigate influencing factors oblique incidence P waves. show angle incidence, location interface between soft hard rocks, impedance ratio have significant effects landslide.
