GeoSlope International has a nice overview of the general limit equilibrium (GLE) method in their February 2007 newsletter available from their website. I personally always struggle to remember the difference between the various methods of slope stability analysis, such as Bishop’s method, Janbu’s method, GLE, Spencer’s and Morgensten-Price. This article has a couple of nice figures showing how they all relate to each other and what that means for the factor of safety.

Side Hill Retaining Walls – Part 1
Side-hill retaining walls refer primarily to fill-walls built partway down the sides of an existing slope or embankment. They are encountered in roadway and rail widening projects as well as site development but usually in steep terrain. This article provides an overview of the problems, failure mechanisms, investigation approaches, analysis tools and wall type alternatives for these structures. Click through to read the article!
