| مستخلص: | This is an Accepted Manuscript of an article published by Taylor & Francis Group in Geomechanics and geoengineering on 2019, available online at: http://www.tandfonline.com/10.1080/17486025.2018.1490460Test The undrained stability of slopes in anisotropic fine-grained soils is studied in this paper using the finite element method (FEM). A constitutive model is presented, able to account for the observed variation of undrained strength with loading direction. The model is able to encompass the different strength distributions observed in normally, slightly overconsolidated and heavily overconsolidated soils. A series of stability analyses have been performed to explore the effect of the type of undrained strength anisotropy on the stability and failure mechanisms of slopes of different inclinations. In addition, a real case study of the failure of an underwater slope is analysed with the numerical approach presented. It suggests that, by considering undrained strength anisotropy, the failure can be satisfactorily explained. Peer Reviewed Postprint (author's final draft) |
