In this study, new empirical predictive relationships for earthquake-induced crest settlement of earth-core rockfill dams (ECRDs) were developed. A case history database of 19 dams that had been subjected to earthquakes was utilized. The presented relationships correlate the intensity measure (IM) of the earthquake records with the observed ...

Dams are structures designed primarily for water containment. They usually are found in areas with special transportation needs, either for mining purposes or for transporting heavy equipment, and with limited road infrastructure available. Heavy traffic over dams is discouraged, due to the damage this can cause to the integrity of the structure.

Internal erosion of dam’s embankments is a complex process and considered as the main cause of hydraulic works failure. Laboratory experiments provide a potential insight into the processes involved. Particles detachment from a core of earth and rock fill dams within a crack submitted to water seepage may lead to backward erosion which gradually ...

Seepage and Pore Pressure in the Core of a Earth-and-Rockfill Dam
Power Technology and Engineering, 2016A numerical solution to the anisotropic seepage problem for an earth dam is examined. Results are presented for solution of the problem and analysis of the stability of an earth dam slope with due regard for the influence seepage anisotropy.

Research on New Dam Structure for High Earth Core Rockfill Dam on Thick Overburden
IACGE 2013, 2013For high earth core rockfill dam constructed on thick overburden, traditional anti-seepage system design and construction is to construct the foundation seepage cut-off wall first, and then build a rigid or soft-connected grouting gallery on top of seepage cut-off wall, and then cover the gallery with high plastic clay.

Influence of thickness of a vertical core on the slope stability of earth and rockfill dams
Dams and Reservoirs, 2014An analytical study was undertaken to identify the zone within which the thickness of a vertical core has no influence on the stability of upstream and downstream slopes of earth and rockfill dams. Stability analysis was carried out for a 180 m high earth and rockfill dam on strong foundation.

Quality Control Aspects for Casing Material and Coarse Filter for Earth Core Rockfill Dam
2021Blasted prototype rockfill material from a multipurpose irrigation project which is under construction in India is considered for its quality control / assurance for this paper. The maximum particle size (dmax) of blasted rockfill material used in construction of the above project is 600 mm, and the maximum particle size of inclined and horizontal ...

Rockfill Dams: Dams with Sloping Earth Cores
Journal of the Power Division, 1958This paper briefly reviews the principles which govern the design of a rockfill dam and discusses six rockfill dams with which the author has been intimately acquainted since completion of the Nantahala Dam. Bear Creek Dam, one of these six, incorporates most improvements in design and construction learned from experience.

Many high earth rockfill dams are currently being constructed in the alpine region of Southwest China. Since the effective working time is reduced by the cold climate, it is necessary to solve the problem of intermittent filling of the core wall at low temperature.

Geotechnical investigation of geomaterials is one of the most important tools to arrive at safe and economical design of structures. Inadequate investigations many times result in non-optimal geotechnical solutions. Encounterence of geological surprises and adverse geological occurrences result in cost overrun and sometimes even compromising safety of ...
