Fractures in non-homogeneous rockfill materials from a micromechanics perspective [PDF]

open access: yesJournal of Hydraulic Structures, 2022
This study investigates particle breakage and cracks propagation of non-homogeneous rockfill materials, particularly conglomerates, from a microscale perspective. The conglomerate's materials were gathered from Masjed-E-Soleyman, MES, rockfill dam, Iran.

A Study of the Rockfill Material Behavior in Large-Scale Tests [PDF]

open access: yesCivil Engineering Infrastructures Journal, 2013
Inspecting the behavior of the rockfill materials is of significant importance in analysis of rockfill dams. Since the dimensions of grains in such materials are greater than the conventional sizes suitable for soil mechanics tests, it is necessary to ...

Dilatancy behaviors of rockfill materials considering particle breakage

open access: yesYantu gongcheng xuebao, 2021
In order to study the relationship between particle breakage and dilatancy characteristics of rockfill materials under different porosity and stress conditions, the large-scale triaxial tests are carried out on the rockfill materials of a high rockfill ...

Damage evolution mechanism and safety evaluation criterion of ultra-high rockfill dam system under strong earthquakes

open access: yesYantu gongcheng xuebao, 2022
Several ultra-high earth and rockfill dams up to 250 to 300 m in height are to be built in the intensive earthquake regions of West China. The strong outburst and high uncertainty of strong earthquakes pose a great threat to the safety of ultra-high ...

Experimental Study on Grouting Effect and Mechanical Properties of the Rockfill Materials Grouted with SCM

open access: yesAdvances in Civil Engineering, 2020
Insufficient compactness of rockfill materials may potentially cause excessive deformation of a concrete face rockfill dam (CFRD), thus resulting in cracking of the face slab and leakage of the dam body, thereby requiring reinforcement treatment. To date,

Study and application of control indices for filling quality of high concrete face rockfill dams

open access: yesYantu gongcheng xuebao, 2020
Based on the filling gradation of rockfill of Aertashi high concrete face dam under construction, field large-scale relative density tests are carried out. The three-factor map is used to study the design method of the double-control filling standards of

Collapse of rockfill

open access: yesInternational Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1991
Os materiais de enrocamento exibem deformações devidas à molhagem ou saturação. Nesta comunicação são apresentados resultados de enrocamentos de baixa e elevada resistência ensaiados em cmaras de compressão unidimensional e compressão triaxial com vista à quantificação do fenómeno.
