Assessment of Real-Time Compaction Quality Test Indexes for Rockfill Material Based on Roller Vibratory Acceleration Analysis [PDF]
Compaction quality is directly related to the structure and seepage stability of a rockfill dam. To timely and accurately test the compaction quality of the rockfill material, four real-time test indexes were chosen to characterize the soil compaction ...

Calibration and performance of two different constitutive models for rockfill materials
In this paper, two different concepts for the constitutive modeling of the mechanical behavior of creep-sensitive rockfill materials are presented. Specifically, the performance of an extended generalized plasticity model proposed by Wang is compared ...

A three-dimensional elasto-plastic dynamic response procedure for concrete-faced rockfill dams
Equivalent linear dynamic analysis is the primary method of analysis for concrete-faced rockfill dams during earthquake. However, this method cannot be directly used to estimate permanent deformation during earthquake, which is important to evaluate the ...

Extrapolation-Based Scale Effect Model for Granular Heap Modulus
The numerical analysis was used to predict the rockfill dam displacement, and the model parameters were calibrated using the triaxial experiments on scale-down rockfill samples. Due to the scale effect of rockfill material, the displacements were usually

Hydraulic and structural evaluation of rockfill dam behavior when exposed to throughflow and overtopping scenarios [PDF]
Dams are vulnerable to extreme flood events in turn leading to accidental overtopping. This inparticular applies to rockfill dams comprised of pervious and erodible material.

Testing and modeling of rockfill materials: A review
AbstractThe research development of rockfill materials (RFM) was investigated by a series of large-scale triaxial tests. It is observed that confining pressure and particle breakage play important roles in the mechanical property, dilatancy relation and constitutive model of RFM.
