A method for calculating permanent displacement of seismic-induced bedding rock landslide considering the deterioration of the structural plane

The mechanism of seismic-induced bedding rock landslide is distinct from that slope instability/landslide in normal gravity conditions; their failure modes are mainly characterized by vibration deterioration effect mass structural plane due to a seismic loading, which has significant on the stability landslide. Several advanced methods have been proposed assess earthquake-induced However, quantitative evaluation plane, along with its application dynamic analysis slopes, remains challenging topic requires further study. In this study, basic cyclic shear condition and test expressions calculate dilatancy angle friction under loading studied. A formula for strength proposed, fully considers during shear. Furthermore, new calculating method permanent displacement landslide, introduces developed. case study was used compare calculated those obtained using Newmark Qi methods, demonstrates effectiveness applicability method.
