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.

Construction and Analysis of Slope Plane Deformation of High CFRD Based on Statistical Analysis of Multi‐Points Monitoring Data

Engineering Reports, Volume 7, Issue 3, March 2025.
This study proposed a method of modeling and analysis of dam slope plane deformation based on multi‐points monitoring data. Firstly, based on the sort out and analyze of actual monitoring data of the Hongjiadu CFRD, the deformation property of the dam has been mastered.

Effect of uncertainties in breach location and breach mechanisms on risk‐related classification of off‐stream reservoirs

Journal of Flood Risk Management, Volume 18, Issue 1, March 2025.
Abstract Off‐stream reservoirs are artificial water storage structures that increase the flood risk of an area. In some places, related risk reduction plans are based on a risk classification of these structures, which follows local water resource management regulations. These classification methods typically follow deterministic qualitative guidelines

Study of Stress and Deformation of High Concrete-Face Rockfill Dam on Steep Slope in Narrow Valley

Renmin Zhujiang, 2022
At present,in the finite-element stress and strain calculation of rockfill dams,fixed support is mostly adopted to simulate the connection between the rockfill at the bank slope and the slope.As for a concrete-face rockfill dam (CFRD) in the steep slope ...

Experimental Study of Dike‐Break Induced Flow Generated by Instantaneous Opening of the Side Gate

Journal of Flood Risk Management, Volume 18, Issue 1, March 2025.
ABSTRACT A large‐scale experimental model of instantaneous dike‐break induced flow was conducted in this work. Water level variations in the river channel and floodplain, breach discharge, and the surface velocity field at the breach were measured during dike failure.

The compressive creep of rockfill

, 2023
Abstract Multistage constant stress rates loading-creep tests were carried out on air-dried slate rockfill. The influences of the loading history on the creep deformation of rockfill were investigated, including the prior loading stress rate, the stress increment size of prior loading, and the history of early loading and early creep, in which '

Coarse‐Grained Ore Distribution on Conveyor Belts With TRCU Neural Networks

IET Image Processing, Volume 19, Issue 1, January/December 2025.
(1) The method can be used as technical support and the basis for subsequent real‐time particle size detection in the beneficiation process. (2) The proposed model combines Transformer and residual blocks with the CBAM attention mechanism in the encoder‐decoder. (3) The proposed model can effectively partition the ore particles of different grain sizes.

Variation of stress-strain state of rockfill dam affected by creeping

Magazine of Civil Engineering
Rockfill is subject to creeping and this phenomenon has negative consequences for rockfill dam stress-strain state (SSS). Recently, rockfill creeping attracts more and more attention in China where a great number of embankment dams are constructed ...

Experimental study on effect of scaling on compact density of coarse-grained soils

Yantu gongcheng xuebao, 2019
There is a certain difference in compact density of rockfill materials between the real gradation and corresponding scaling gradation. In order to describe the difference quantitatively, the scaling effect can be divided into two parts, changes of the ...
