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.

TL;DR: In this article, a 3D slope stability analysis is performed by the strength reduction method (SRM) and the limit equilibrium method (LEM) for simple slopes, and the authors have discovered many interesting results which appear to be surprising, but a more detailed analysis by the SRM and LEM along with some physical insight have suggested that these results may be true for simple slope.

TL;DR: Use of a modified particle swarm optimization method with a termination criterion is proposed and is demonstrated to be effective and efficient in solving complicated problems with a high level of confidence.

TL;DR: In this article, the critical slip surface is divided into two parts when the pile spacing is small, and these two parts gradually get connected with the increase of pile spacing until a clear critical slip surfaces is formed.

TL;DR: In this article, a detailed study of nailed slopes under different conditions is reported, and no major difference is found in terms of safety and slip surfaces between the strength reduction method (SRM) and the limit equilibrium method (LEM) in general cases.
