Large-scale triaxial test study on wetting deformation characteristics of rockfill materials
Shuili Shuiyun Gongcheng Xuebao, 2023 The wetting of rockfill material can easily lead to the uncoordinated deformation between it and the core wall, thus causing longitudinal cracks at the top of the dam and endangering the safety of the dam.

Experimental study on strength and deformation characteristics of gravelly soil core materials
Yantu gongcheng xuebao, 2020 For the earth core rockfill dam, the coordination of the strength and deformation of the dam is a key issue that restricts the dam construction. The deformation of the gravelly soil core materials is large, which leads to the transfer of the load to the ...

Inverse Parametric Analysis of Seismic Permanent Deformation for Earth‐Rockfill Dams Using Artificial Neural Networks [PDF]
Mathematical Problems in Engineering, 2012 This paper investigates the potential application of artificial neural networks in permanent deformation parameter identification for rockfill dams. Two kinds of neural network models, multilayer feedforward network (BP) and radial basis function (RBF) networks, are adopted to identify the parameters of seismic permanent deformation for Zipingpu Dam in

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.ABSTRACT The reliability of flood event simulations is a crucial aspect in terms of saving lives. The worst flood scenarios derive from possible dam failures. For earthen dams, the breaching mechanism, triggered by overtopping or piping, is affected by several modelling uncertainties, which propagate downstream and may influence flood hazard mapping ...

Geofluids, Volume 2026, Issue 1, 2026.Reservoir seepage is a critical issue that must be addressed during the design phase of water conservancy projects. Based on engineering geological and hydrogeological investigations, a three‐dimensional geological model was established for a dam site in the Huaihe River Basin.

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.
