A Method for Determining the Displacement Monitoring Index for Rockfill Dams Considering Material Uncertainty

open access: yesApplied Sciences
To consider the influence of material parameter uncertainty on the structural deformation of a dam effectively and to establish a reasonable and reliable safety monitoring index for the displacement of a rockfill dam, a method for determining the ...

Assessment of Real-Time Compaction Quality Test Indexes for Rockfill Material Based on Roller Vibratory Acceleration Analysis [PDF]

open access: yesAdvances in Materials Science and Engineering, 2018
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 ...

Discrete element simulation of crushable rockfill materials [PDF]

open access: yesWater Science and Engineering, 2013
A discrete element method was used to study the evolution of particle crushing in a rockfill sample subjected to triaxial shear. A simple procedure was developed to generate clusters with arbitrary shapes, which resembled real rockfill particles.

Hydraulic and structural evaluation of rockfill dam behavior when exposed to throughflow and overtopping scenarios [PDF]

open access: yes, 2020
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.

Application of fractal theory in rockfill rheology

open access: yesShuili Shuiyun Gongcheng Xuebao, 2017
The rockfill material crushes during the process of rheology and the fractal dimension of rockfill material varies with time. Based on the basic rule of rheological process of coarse-grained soils, the fractal theory is applied into the analysis of ...

Effect of Normal and Shear Interaction Stiffnesses on Three-Dimensional Viscoplastic Creep Behaviour of a CFR Dam

open access: yesAdvances in Civil Engineering, 2018
Rockfill materials and foundation continuously interact with each other during lifetime of the rockfill dams. This interaction condition alters the viscoplastic behaviour of these dams in time.
