Simulation method for crest cracks in high earth core rockfill dams and its application
Yantu gongcheng xuebao, 2020 The crest cracks are the common dangers during construction and operation of high earth core rockfill (ECRD) dams. The occurrence and propagation of the crack increases the safety risk of the project greatly.

Research on Criterions of Hydraulic Fracturing in Earth Core Rockfill Dams
IOP Conference Series: Earth and Environmental Science, 2019 Abstract Hydraulic fracturing is an important destruction mode in the earth core rockfill dam engineering. In this paper, to explicit the mechanism of hydraulic fracturing and thus to verify the existing criterions, hydraulic fracturing tests were conducted based on true triaxial apparatus.

Soils and Foundations, 2022 This study investigates three aspects of the dynamic response of earth-core rockfill dams (ECRDs) under earthquake loadings, including induced shear strain, increased fundamental period, and shear modulus reduction. A database of the recorded ground motions of ECRD cases in Japan is analyzed to carry out this study.

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 ...
