in the first impounding of rockfill dams, additional settlements occur in upstream side in saturated rockfills due to collapse phenomenon even high rainy seasons can cause additional deformation in the dumped rockfills. unfortunately these displacements are not taken into account in the conventional numerical models which are currently used to predict embankment dam behavior during impounding. ...

construction of asphaltic core dams is a relatively novel method especially in iran. iran is located in a region with high seismicity risk. therefore, many researchers have focused on the behavior of such types of dams under earthquake loading. in this research, the behavior of asphaltic core rockfill dams (acrd) has been studied under earthquake loading using nonlinear dynamic analysis method ...

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...

Abstract The use of carbon nanotubes (CNTs) to reinforce cemented rockfill is attracting considerable interest due the remarkable improvement in performance and extremely low dose added nanomaterial. To reveal enhancement mechanism CNTs on rockfill, acoustic emission (AE) characteristics specimens during Brazilian split test were investigated. results demonstrated that improved tensile strength...

Among the structural and non-structural methods of flood control, rockfill dams are a kind of detention structures that increase travel time and reduce the maximum instantaneous flood discharge. Due to the rapid and automatic effect of these dams, flood reduction happens more quickly. In this research, the best arrangement of rockfill dams at Taleghan basin was determined based on the cost of r...
