New criteria for defining slope failure using the strength reduction method
TL;DR: In this paper, the authors developed several new slope failure criteria that are based on energy change, which is closely related to the slope failure driven by energy, and the reliability of the proposed criteria is verified using 2D and 3D slope cases.

Numerical analyses of stability and deformation behavior of reinforced and unreinforced tunnel faces
TL;DR: In this article, a numerical study of both unreinforced and reinforced tunnel excavation faces by means of 3D FEM analyses is presented, and the results are compared with those of the traditional limit equilibrium method and with an analytical solution based on previous numerical studies.

Probabilistic analysis of reinforced slopes using RFEM and considering spatial variability of frictional soil properties due to compaction
Ning Luo,Richard J. Bathurst +1 more
TL;DR: Probabilistic stability analyses of constructed wrapped-face reinforced slopes (or embankments) using frictional soils were carried out using the random finite element method (RFEM).

Finite element analysis of undrained stability of cantilever flood walls
TL;DR: In this article, a finite element analysis with a two-dimensional plane strain condition was performed on cantilever flood walls in homogeneous and non-homogeneous clay layers, where the latter corresponded to a linear increase in shear strength with depth.

Strength reduction method in Barodesy
TL;DR: In this article, a strength reduction method for the barodetic material model is introduced and the results of slope stability calculations compared with the results with an elasto-plastic material model (M ohr -C oulomb ) and with the result of an analytical analysis according to B ishop are presented.

The influence of strains in soil mechanics
TL;DR: In this paper, the load-deformation behavior of soils in mixed boundary value problems at model scale is discussed. But the main objective is to develop an understanding of the stress-strain behaviour of soils so that reliable predictions can be made concerning their load deformation characteristics at all working loads, rather than only loads at failure.

Lower bound limit analysis using finite elements and linear programming
TL;DR: In this article, a technique for computing lower bound limit loads in soil mechanics under conditions of plane strain is described, where a perfectly plastic soil model is assumed, which may be either purely cohesive or cohesive-frictional, together with an associated flow rule.
Journal ArticleDOI
Two-dimensional slope stability analysis by limit equilibrium and strength reduction methods
TL;DR: In this paper, the factors of safety and the locations of critical failure surfaces obtained by the limit equilibrium method and strength reduction method are compared for various slopes, and it is found that the results from these two methods are generally in good agreement except when ϕ′ is zero.
Journal ArticleDOI
Geotechnical stability analysis
TL;DR: In this paper, the authors describe recent advances in stability analysis that combine the limit theorems of classical plasticity with finite elements to give rigorous upper and lower bounds on the failure load.
