Effect of dry-wet cycles on the strength and deformation of the red-bed rockfill material in western Yunnan

open access: yesFrontiers in Earth Science, 2023
Introduction: The shear strength deterioration of red-bed rockfill under the dry-wet cycle is the key factor affecting the slope stability of accumulation body.

An experimental study of the behaviour of two rockfills accounting for the effects of degree of saturation [PDF]

open access: yesE3S Web of Conferences, 2020
Rockfill dams have become more and more recognized for their safety, economy and adaptability to widely varying site conditions. As a contribution to the understanding of the main factors affecting the rockfill behaviour, the paper reports and discusses ...

A predictive method for the shear strength—displacement behavior of rockfill materials [PDF]

open access: yesREM: International Engineering Journal
Rockfill material is widely used in the construction of rockfill dam bodies, protective slope linings, and drainage systems, as well as in the stabilization of natural slopes. This material possesses high mechanical strength, excellent durability against

Experimental Study and DEM Simulation of Size Effects on the Dry Density of Rockfill Material

open access: yesFrontiers 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.

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.

The Role of Nature of Particles on the Behaviour of Rockfill Materials

open access: yesSoils and Foundations, 2006
The nature of the particles of seven alluvial rockfill materials and three quarried rockfill materials are expressed in terms of uncompacted void content and unconfined compressive strength of each of the rockfill materials. Drained triaxial tests are conducted on modeled rockfill materials.

Study on the Early Warning Methods of Dynamic Landslides of Large Abandoned Rockfill Slopes

open access: yesApplied 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.

Suction effects on rockfill compressibility [PDF]

open access: yes, 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

open access: yesAdvances 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.

Experimental study on filling standard of high rockfill dams with soil core

open access: yesYantu 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 ...
