Computational modeling plays a significant role in the design of rockfill dams. Various constitutive soil parameters are used to such models, which often involve high uncertainties due complex structure dams comprising various zones different parameters. This study performs an uncertainty analysis and global sensitivity assess effect on behavior dam. A Finite Element code (Plaxis) is utilized f...

The establishment of relationships between the shear wave velocity (V s ) and other geotechnical parameters rockfills under large strains (e.g., oedometer-constrained modulus, M oedo , tangent elastic E t is a significant step toward precise modeling earth structure stress–strain behavior. In this study, four specimens reconstituted from rockfill used for Romaine-2 dam construction were investi...

Stress relaxation properties have a significant impact on the performance of polyvinyl chloride (PVC) geomembranes (GMBs) at peripheral joints membrane faced rockfill dam (MFRD). This paper presents fractional order viscoelastic model (FOVM) to measure stress as function time. Model parameters were obtained by best fit results from wide-width strip tensile tests conducted three rates and initia...
