The rockfill toe structure situated within the downstream slope of dams is an integral part a defense mechanism safeguarding dam in throughflow situations. Recent studies have concluded that can significant impacts on development and stability under scenarios accidental caused by overtopping core. ability to numerically model effect various configurations flow through support design effective d...

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...

detention rockfill dams are an easy and common tool for flood control. due to their coarse pores, the flow in void spaces is turbulent and non-darcy. different relationships introduced by researchers are used to define the hydraulics of the flow within the rockfill materials. the present research is aimed at gaining a better understanding of the differ-ence among these relationships and the sou...

Dams and ponds as engineering structures pose various risks during design, construction operation. Deformation in dams, slope stability problems or excessive pore pressure can cause serious damage that cannot be prevented. It is critical to position these areas correctly evaluate the potential quantitatively. In rockfill work needs done planning project phase, especially on infiltration safety....
