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...

Numerous stepped spillways were built to date, namely on RCC gravity dams or on valley flanks besides embankment or rockfill dams, while some others are currently under design or construction. In some cases, slope changes may be required on stepped chutes, due to the topography, leading to reduced excavation and related economic benefits. A quite limited number of stepped spillways have been bu...

During construction of concrete faced rockfill dam (CFRD), the extrusion-sidewall will be protruding or deficiency under normal. Before panel construction, local slope cutting should taken for squeezed side wall supplementary filling measures after excavating wall, which affect mechanical deformation panel. According to monitoring data concrete-faced dams some hydro-electric station in Hubei Pr...

Tailings dams, due to methods and materials used in their construction are vulnerable structures to earthquake. In many cases storage of water over tailings is required to prevent aerial pollution or reduction in water consumption by the means of a recycling system, therefore failure of these kinds of dams not only induce affects similar to conventional water dams, but also may lead to irrevers...

The electrical resistivity tomography technique is a geophysical inspection method widely used for several investigations, such as mining exploration, fault localization, groundwater flow, geological and pollution zones. Infusing brine into substructure can increase conductivity becomes useful medium to trace the path of seepage flowing in rockfill dams. In this article, an elapsed-time was dev...

seismic behavior of a rockfill dam with asphalt-concrete core has been studied utilizing numerical models with material parameters determined by laboratory tests. the case study selected for these analyses, is the meyjaran asphalt core dam, recently constructed in northern iran, with 60 m height and 180 m crest length. the numerical analyses have been performed using a nonlinear three dimension...
