Eighth International Conference on Case Histories in Geotechnical Engineering
Finite Element Studies of an Earthquake-Induced Landslide Using Different Plastic Flow Rules
Publication: Geo-Congress 2019: Earthquake Engineering and Soil Dynamics (GSP 308)
ABSTRACT
Many landslide masses are inhomogeneous and complicated. To a limited level, the failure mechanism, such as the initiation time and threshold displacement, derived from classical constitutive models and numerical methods could be further discussed to ascertain its applicability. In this paper, a validated dynamic finite element procedure is employed to analyze a coseismic landslide subjected to earthquake loading. The sliding mass and slope are expressed using quadrilateral elements of elastoplastic behavior that obey Mohr-Coulomb criteria with associative and nonassociative plastic flow rules. Based on the results, the flow rule does not have a major influence on discriminating the initiation time but have significant impact on the coseismic deformations during ground motion. Our analysis provides preliminary investigation focusing on the earthquake-induced landslide considering different plastic flow rules.
