Suction effects on rockfill compressibility [PDF]
, 2003 A conceptual mechanism of rockfill deformation was postulated by Oldecop & Alonso (2001) on the basis of the observed rockfill behaviour in suction-controlled oedometer tests.

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.

Calibration and performance of two different constitutive models for rockfill materials
Water Science and Engineering, 2016 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 ...

Dependence of shape on particle size for a crushed rock railway ballast [PDF]
, 2013 Laboratory testing of railway ballast poses practical difficulties because the particle size is often too large for most standard apparatus. There are therefore advantages in developing a scaled material whose behavior is representative of the full size ...

Study on the Early Warning Methods of Dynamic Landslides of Large Abandoned Rockfill Slopes
Applied Sciences, 2020 The excavation of large-scale underground projects produces a large amount of rubble waste material that is temporarily deposited near the project site, which forms a large-scale waste rockfill artificial slope.

Experimental Study and DEM Simulation of Size Effects on the Dry Density of Rockfill Material
Frontiers in Physics, 2022 The initial dry density has a significant effect on the mechanical behavior of rockfill material (RFM). The size effects on the minimum/maximum dry density (referred to as dry density, ρd) of RFM still need further study.

A three-dimensional elasto-plastic dynamic response procedure for concrete-faced rockfill dams
International Journal of Distributed Sensor Networks, 2018 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 ...

Experimental study on filling standard of high rockfill dams with soil core
Yantu gongcheng xuebao, 2019 The monitoring data of high ECRDs have shown that the deformation coordination in dam material zones does not meet the design goal, which is related to the degree of matching in the current specifications of filling for the filtration zone, transition ...
