Dam failures are examples of man-made disasters that have stimulated investigation into the processes related to failure different dam types. Embankment breaching during an overtopping event is one major modes for this type, comprising both earthfill and rockfill dams. This paper presents results a series laboratory tests on breach initiation progression in Especially eight 1 m-high 1:10 scale ...

The site for the high Quxue Dam has a narrow canyon with very steep abutments and complex geology in Sichuan Province, China. Various types of embankment concrete dams were considered an asphalt-core dam (ACED), 174 m high, was selected. asphalt core is slender impervious element some concerns have been raised about reliability safety type (ACEDs). This paper presents case study highest ever bu...

having observed the costly failures of different cutoff walls, that had been constructed according to the mix design specified by reputable consultants in iran, a research programme was conducted to study the effects of constituent materials on the properties of plastic concrete. the main properties, such as compressive strength, biaxial and triaxial strains, permeability, and modulus of elasti...

detention rockfill dams are accounted as economically efficient structures for flood control, river bed and banks protection, flow diversion, etc. as the hydraulic behavior of these structures, when are used for flood control, is affected by the depth of water in their porous media, there are interests to predict water surface profile through the body of these structures. in this research, we d...

Abstract Rockfill dams with stone pitching are specific hydraulic structures generally built in the early XXth century where stones used to be hand‐placed without mortar constitute upward and downward dam faces. Few studies have been carried out quantify critical role of stability against both static seismic forces. Herein, a numerical model is proposed pseudo‐static tests performed on four dif...
