Study on safety of a high earth-core rockfill dam considering contact effect between dam and foundation

Shuili Shuiyun Gongcheng Xuebao, 2019
With a traditional method to calculate the stress and deformation of earth-rock dam, the contact effect between the dam and the bedrock is neglected, which is not consistent with the actual condition.

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

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.

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.

Seismic responses of high concrete face rockfill dams: A case study

Water Science and Engineering, 2016
Seismic responses of the Zipingpu concrete face rockfill dam were analyzed using the finite element method. The dynamic behavior of rockfill materials was modeled with a viscoelastic model and an empirical permanent strain model.
