Summary:
An analytical investigation was conducted to evaluate the geotechnical safety and stability of MSW landfills constructed with significantly steepened slopes achieved through geosynthetic reinforcement. The primary motivation for this endeavor was to propose a new design/construction methodology for innovative expansion of landfill capacity. A 2-D plane strain linear elastic analysis was performed with ANSYS finite element software on full-scale MSW landfill structures (with and without geogrids), having slopes of 1:1, 1:2, and 1:3. Both local and global factors of safety were determined employing the Mohr-Coulomb failure criteria, and compared with traditional solutions using the Bishop's Modified Method. It was found that the landfill slopes could be steepened up to 1:1 using geogrid reinforcement, resulting in higher storage capacity and consequential environmental and economic benefits.
