New Type of Dam for Longitudinal Reinforced Rockfill Dam and Its Operation Safety Analysis

open access: yes工程科学与技术, 2019
After a long time operation, a conventional earth rockfill dam (e.g. homogeneous dam or core wall dam) may suffer from a lot of dam diseases such as dam-break, overtopping, landslides and leakage. On the basis of a large number of practices of rebuilding

Evaluation of anti-explosion performance of Shuibuya concrete-faced rockfill dam slabs subjected to strong shock waves caused by an underwater explosion

open access: yesAdvances in Mechanical Engineering, 2019
A concrete plastic-damage model, the extended Drucker–Prager model for rockfill, and acoustic elements for water were introduced and applied to the impact fracture analysis of a concrete-faced rockfill dam–water three-dimensional system.

Comprehensive review of innovative construction technology of high‐core rockfill dam: Nuozhadu project

open access: yesRiver, Volume 4, Issue 2, Page 135-148, May 2025.
Abstract Underpinned by the ultrahigh‐core rockfill dam at the Nuozhadu Hydropower Station, comprehensive studies and engineering practices have been conducted to address several critical challenges: coordination of seepage deformation in dam materials, prevention and control of high‐water‐pressure seepage failure, static and dynamic deformation ...

Geophysical imaging of the subsurface seismic structure of the Chestnut Hill Reservoir earth embankment dam (Massachusetts)

open access: yesNear 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 ...

A machine vision‐based intelligent segmentation method for dam underwater cracks using swarm optimization algorithm and deep learning

open access: yesComputer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 10, Page 1405-1417, 18 April 2025.
Abstract Ensuring the safety of water networks is a research hotspot in the current water conservancy industry, and dams are an important part. However, over time, the dam is prone to varying degrees of aging and disease, most of which are structural cracks.

Seismic responses of high concrete face rockfill dams: A case study

open access: yesWater 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.

Construction and Analysis of Slope Plane Deformation of High CFRD Based on Statistical Analysis of Multi‐Points Monitoring Data

open access: yesEngineering 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.

Effect of uncertainties in breach location and breach mechanisms on risk‐related classification of off‐stream reservoirs

open access: yesJournal 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
