Development and initial application of test devices for leakage of earth-rockfill dams
Yantu gongcheng xuebao, 2023 To accurately simulate the seepage characteristics of earth-rockfill dams during leakage, a test device is developed. The device can precisely control the test variables such as platform slope, water supply discharge, water temperature, etc.

Journal of Engineering, Volume 2026, Issue 1, 2026.Accurate prediction of seepage pressure head is essential for assessing the integrity of concrete‐faced rockfill dams (CFRDs), particularly for CFRDs serving as reservoir basins of pumped‐storage power stations, where daily water‐level fluctuations of tens of meters make seepage losses a direct threat to generation efficiency.

Non-linear response of the rockfill in a concrete-faced rockfill dam under seismic excitation
, 2014 This study investigates the non-linear response of the rockfill in a concrete-faced rockfill dam under seismic excitation for various concrete slab thicknesses from 30 to 100 cm thick. The effect of the friction in the concrete slab rockfill interface on

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.The unclear impact of temperature on rockfill dam settlement and the lack of a solid basis for selecting temperature parameters in prediction models are problematic. These issues significantly limit the accuracy and applicability of deformation monitoring models for rockfill dams.

Water Resources Research, Volume 61, Issue 11, November 2025.Abstract Addressing the limitations of traditional overtopping risk analysis methods, which either consider only a single failure mode or fail to accurately characterize the nonlinear characteristics of reservoir levels, this paper proposes a novel overtopping risk model for dams.

Supervised parameter updating of deformation analyses for rockfill dams using prior knowledge
Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 26, Page 4583-4606, 7 November 2025.Abstract Accurate and reliable numerical simulation is crucial for the safe construction and operation of infrastructure such as rockfill dams. Model parameter updating through inverse analysis based on monitoring data is key to improving analysis accuracy.

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 ...
