Dynamic response of rock slopes to oblique incident SV waves

摘要: Abstract Most dynamic response analyses of rock slopes only consider the vertical incidence seismic waves. However, obliquely incident waves dominate in near-field areas. This paper presents a new input method that considers oblique based on mechanisms artificial viscous boundaries and influence angle slopes. Three numerical model with different slope angles 30°, 45° 60° are excited El Centro earthquake record assuming varying from 0° to 90°. The results show significantly affects most damaging directions approximately perpendicular surface, rather than direction. will be underestimated if is considered. reflection wave field areas affected by decrease increasing angle. predominant period spectrum not sensitive location. study unveils mechanism earthquake-induced slides, which significance for hazard prevention.
