Probabilistic Assessment of Soil–Rock Mixture Slope Failure Considering Two‐Phase Rotated Anisotropy Random Fields

International Journal for Numerical and Analytical Methods in Geomechanics, Год журнала: 2024, Номер unknown

Опубликована: Дек. 16, 2024

ABSTRACT Soil–rock mixture (SRM) slopes consist of soils and rocks are widely distributed globally. In addition to heterogeneity discontinuity within SRM slopes, the inherent spatial variability can be observed in soil rock properties. However, properties layouts has not been well considered stability analysis slopes. Additionally, commonly show a rotated anisotropic fabric pattern, while such rarely accounted for slope analysis. this study, two‐phase anisotropy random field simulation method is proposed model these variations simultaneously. The approach then integrated with finite element (FEM) study impacts volume fraction bedding dip angle (i.e., anisotropy) on probability failure ( p f ) mode It found that considering only spatially varying underestimate by up 97% compared both variable layouts. increase significantly improves likelihood deep failure. greatly influences , yet remains dominant across different angles. Furthermore, more sensitive changes than angle.

Reliability analysis using Limit equilibrium and Smoothed Particle Hydrodynamics-based method for homogeneous soil slopes

PLoS ONE, Год журнала: 2024, Номер 19(3), С. e0300293 - e0300293

Опубликована: Март 11, 2024

This paper develops a combined method to predict the volume of sliding mass for homogeneous slopes in an efficient manner. Firstly, failure surface with minimum factor safety (FS) Limit Equilibrium Method is equated that one determined by Smoothed Particle Hydrodynamics algorithm obtain threshold displacement value unstable and stable particles. Secondly, used identify using SPH. Finally, regression model developed based on finite number SPH simulations soil slopes. The proposed LEM-SPH illustrated through cohesive slope. It concluded use FS LEM tends underestimate give unconservative risk value. Coefficient Variation (Cov) are 0.14, 0.28, 0.4, 0.48, 0.53 Cov properties = 0.2, 0.3, 0.5, 0.6, respectively. uncertainty has significant effect mean therefore landslide necessitated cases where large uncertainties exist.
