Stability Analysis When Using an Engineered Berm to Increase Landfill Space

Abstract

The scope of this paper is to develop a new three-part wedge method to analyze translational failure when using an engineered berm to increase landfill space. The possible failure face may pass over the back slope of the berm or pass under the bottom of the berm. This depends on the geometric dimensions of the berm which in turn influences the amount of airspace gained. Each possible failure condition must be checked to make sure both the waste mass and berm remain stable. If the waste boundary is kept to be unchanged,
