Water Resources Research, Volume 61, Issue 10, October 2025.Abstract The Giant Mine (1948–1999) generated 16 Mt of Au‐bearing mill tailings (2800 mg kg−1) originating from a mixture of flotation tailings (84.8 wt%), calcine residues (14.4 wt.%), and arsenic trioxide roaster waste (0.8 wt.%). A water treatment system for high As mine dewatering effluent has operated since the end of mine operations, with the ...

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.

A characterization model for time‐dependent displacement of concrete dams
Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 23, Page 3707-3725, 19 September 2025.Abstract Time‐dependent displacement caused by creep and shrinkage can significantly affect the structural performance and even shorten the service life of a concrete structure, which is designed for decades or longer, resulting in a safety risk. Unlike in long‐spanning structures such as bridges, where the time‐dependent displacement is readily ...

Filling standards and gradation optimization of rockfill materials
Yantu gongcheng xuebao, 2018 Based on the fractal theory, a large number of relative density tests, compression tests and triaxial tests on rockfill are carried out. The relationships among gradation, dry density, compressive modulus, failure strength and particle breakage of ...

Influence of particle breakage on scale effect of filling characteristics of rockfill material
Yantu gongcheng xuebao, 2020 The filling characteristics of rockfill materials are closely related to their mechanical properties. They can be changed by particle breakage, which is one of the main factors of the scale effect of rockfill materials.

Near Surface Geophysics, Volume 23, Issue 2, Page 105-120, April 2025.Abstract Degradation within a manmade earth embankment structure is often unobservable from the surface. In order to evaluate the structural integrity of earth embankment levees and dams and identify subsurface zones of weakness that may result in the future failures of such structures, various geophysical methods have been proposed as effective ...

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.

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
