Abstract
Aiming at the stability of debris slope, based on the seismic mechanism of friction sliding structure, the fluctuation effect of soil shear strength in earthquake is taken into account in dynamic timehistory response analysis, combining the pseudo-static limit equilibrium analysis with seismic dynamic response based on dynamic strength, the displacement increment and accumulative sliding displacement is acquired with Newmark sliding block displacement method. The results show that the accumulative slippage of plastic sliding in slip direction is more correspond to the actual project. The seismic landslide risk can be discriminated according to the better correlation existing between seismic Newmark displacement and critical acceleration.关键词
