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...

The parameters of the constitutive models used in design rockfill dams are associated with a high degree uncertainty. This occurs because comprised numerous zones, each different soil materials, and it is not feasible to extract materials from such structures accurately ascertain their behavior or respective parameters. general approach involves laboratory tests using small material samples emp...

rockfill dams are accounted as useful measures in watershed management projects. how-ever, the sediment transport through the rockfill materials, could impact their lifetime duration. previously, researches have been conducted to describe the various hydraulically issues of the flow passing through these structures however; there is no general relationship to estimate the sediment transport rat...

The evolutions of practices of seismic slope stability analysis of earth embankment/dam are discussed in this paper. The basic concepts of various methods, salient features, advantages and limitations of each of them are elucidate. Methods for both stability analysis and deformation calculation are presented. Methods for calculation of deformation of post liquefaction stage are also briefed.
