The compressive creep of rockfill
, 2023 Abstract Multistage constant stress rates loading-creep tests were carried out on air-dried slate rockfill. The influences of the loading history on the creep deformation of rockfill were investigated, including the prior loading stress rate, the stress increment size of prior loading, and the history of early loading and early creep, in which '

Engineering Applications of Computational Fluid Mechanics, 2019 Hydraulic designing of rockfill detention dam is based on the treatment of nondarcian and non-linear turbulence flow in coarse porous media. Previous literature focused only on the regular outlet ponds, and there is a shortcoming in the design ...

Modeling Static Behavior of Rockfill Materials Based on Generalized Plasticity Model
Advances in Civil Engineering, 2019 Rockfill materials are commonly used for dam construction. Establishing an effective model that can reasonably describe the mechanical properties of rockfill material is very important for the calculation of earth-rock dam engineering.

A simulation-optimization approach to determine optimum features of detention rockfill dams under flood condition [PDF]
مهندسی منابع آب, 2019 Detention rockfill dams are one of the structural methods that can control flood risks with no impermeable core or membrane. These dams decrease the maximum discharge of flood hydrograph and postpone the time of its occurrence reducing life and financial

Dynamic deformation characteristics of sands and rockfill materials
, 1993 Cyclic torsional simple shear (CTSS) tests and cyclic triaxial (CTX) tests were carried out to investigate the dynamic deformation characteristics of sands and rockfill materials. It was found that the shear modulus and damping ratio can be expressed as

PEMODELAN HYDRAULIC FRACTURE PADA SAAT PENGISIAN WADUK PERTAMA BENDUNGAN ROCKFILL
, 2020 Bendungan rockfill akan mengalami kondisi kritis pada awal pengisian waduk akibat terjadinya hydraulic fracture pada hulu inti bendungan. Hydraulic fracture (retak hidrolis) pada bendungan rockfill terjadi akibat tanah tidak mampu menahan tegangan tarik ...

Geotecnia, 1983 Rockfill material cannot be tested in a natural scale because of the particle size. So there are doubts concerning the accuracy of the laboratory results obtained by the modelling of this material. The main purpose of this work is to contribute to the answer of this question. The minimum size sample that may be tested in laboratory, the parameters used

Study on Hydraulic Fracturing of Core-type Rockfill Dams [PDF]
, 1996 The mecanism of hydraulic fracturing in the core-type rockfill dams was studied in this paper. Series of laboratory seepage fracture tests were carried out on fill materials to investigate the relationship between the hydraulic gradient at failure and ...
