in this study, the mechanical behavior of vanyar dam was evaluated at the end of construction. a two-dimensional numerical analysis was conducted based on a finite element method on the largest cross-section of the dam. the data recorded by the instruments located in the largest cross-section were compared with the results of the numerical analysis at the place of instruments. the settlement, p...
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 ...
کنترل کیفی در پروژه های عمرانی از اهمیت زیادی برخوردار است با این حال علیرغم میل باطنی مهندسین، کنترل کیفی بتن تازه و سخت شده به درستی انجام نمی شود. عدم وجود اطلاعات کافی نزد آزمایشگران و مهندسین موجب می گردد تا در مجموع نتوان کنترل کیفی مناسبی را به اجرا درآورد و یا پس از کسب نتایج مورد نظر نمی توان ارزیابی مناسبی را داشت. موضوع این پایان نامه، کنترل کیفی بتن رویه سد مخزنی شهر بیجار می باشد. ...

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...
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...
