Experimental study on hardening effect of creep in rockfill material
Yantu gongcheng xuebao, 2020 The excessive long-term deformation may lead to crack and damage problems in high earth-rockfill dams. The creep effect of rockfill is crucial for the long-term deformation of rockfill dams.

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 ...

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 ...

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 ...

The Cemented Material Dam: A New, Environmentally Friendly Type of Dam
Engineering, 2016 The first author proposed the concept of the cemented material dam (CMD) in 2009. This concept was aimed at building an environmentally friendly dam in a safer and more economical way for both the dam and the area downstream.
