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 most important features and phenomena of the deformation behavior of rockfills are stress-dependent stiffness, hardening and dilative (or contractive) behaviors, as well as breakage, rotation and redistribution of particle size. An elasto-plastic constitutive model has been suggested by Vermeer and de Borst to simulate the shear behavior of soils, concretes and rocks. This research has trie...

The configuration and safety factor of rockfill dams design depend on materials used in construction the dam. In some regions, available for using as impermeable element dam body are dispersive it is inevitable to consider dispersivity material construction. Internal erosion through cracks or other openings embankment most concern soils. authors have designed an by soil East Africa after finali...
