System Reliability Framework for Design of MSE Walls for Vertical Expansion of MSW Landfills
Publisher: ASCE
Abstract: In the past few decades, waste generation has increased significantly in India, as well as across the globe. Therefore, to avoid the acquisition of new landfill sites, vertical expansion of existing municipal solid waste ...
Effect of Hydrostatic and Hydrodynamic Pressures on the Stability of Landfill Veneer Covers with an Internal Seeper
Publisher: American Society of Civil Engineers
Abstract: The accumulated water in the drainage layer of the municipal solid waste landfill veneer cover system becomes the principal cause of the failure of landfill cover. In this study, seismic stability evaluation is carried out ...
Optimization of Factors of Safety and Displacements of Unsaturated Soil Slopes by the Bioinspired Metaheuristic Method
Publisher: American Society of Civil Engineers
Abstract: The present work introduces an analytical framework based on the limit-equilibrium method for the determination of the local factor of safety (FS) and global factor of safety (FSG), and local displacements along the critical ...
Pseudodynamic Stability Analysis of Landfill Veneer Cover Systems with Clogged Drainage Layer
Publisher: ASCE
Abstract: The accumulated water within the drainage layer of a final cover system of municipal solid waste (MSW) landfills is the foremost reason for the failure of final covers. This study adopts a pseudodynamic (PD) method to ...
Component and System Reliability Assessment of Landfill Cover Systems Using Pseudostatic and Pseudodynamic Methods
Publisher: American Society of Civil Engineers
Abstract: This paper assesses the reliability of landfill veneer cover systems against direct-sliding failure (DSF) and uplifted-floating failure (UFF) modes using the second-order reliability method (SORM). Variability in stability ...
