A Dynamic Analysis of the Interaction of Concrete Face and Rockfill Part in Concrete Faced Rockfill Dams
Introduction Concrete faced rockfill dams have been considered in recent years more than other types of dams due to their low dependency on the bed and the shape of the valley, as well as the simpler construction technology. In this regard, rockfill dams are a suitable substitute for embankment dams because of higher stability of the body and the availability of rock aggregates. On the other h...
متن کاملParametric Evaluation of the Static Stability Analysis of the Asphaltic Concrete Core Rockfill Dams
The present study examined the effect of the geometric parameters of the Rockfill dams on the 2D static analysis of slope stability. In this regard, several numerical models analyzed for eight heights, three slopes of upstream and downstream, three vertical and skewed core thicknesses and four different impounding time stages namely, "End of Construction", "Full Reservoir", "Half Full Reservoir...
متن کاملThe effect of hydrodynamic pressure of the dam reservoir caused by the earthquake on the results of 3D dynamic analysis of concrete face rockfill dams
Concrete faced rockfill dams (CFRDs) are among the structures that due to their advantages such ease of construction and low execution costs,have attracted more attention nowadays.Due to the fact that during large earthquakes,the hydrodynamic pressure will be large and cannot be ignored,the main purpose of this research is to apply reservoir hydrodynamic pressure of dam reservoir caused by the ...
متن کاملSeismic Response of the Kavar Concrete Face Rockfill Dam (RESEARCH NOTE)
This study deals with the dynamic behavior of the kavar concrete Abstract face rockfill damwhich is the first dam of this type to be const ructed in a highly active seismic prone area,situated in the state of Fars southern part of the Islamic Republic of Iran. The finite elementmethod was used as a tool to carry out this study. The finite element discretization was carriedout under plane strain...
متن کاملParticle mechanics modeling of creep behavior of rockfill materials under dry and wet conditions
Keywords: Rockfill creep Particle mechanics method Water weakening Wetting–drying cycles Particle breakage Abrasion a b s t r a c t Rockfill is an important construction material for infrastructure engineering, such as dams, railways and airport foundations, which display a long-term post-construction settlement. However, the main mechanisms for rockfill creep and weathering influence still rem...
