Enhanced Stability and Liquefaction Resistance of Earth Dams With a Proposed Method of Geosynthetic Reinforcements

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
This study evaluates the static and seismic stability of the Narasimharaya Sagar (Gorukallu Balancing Reservoir) earthen dam, located in India’s seismically active Zone II. Using GeoStudio software, seepage, slope stability, and liquefaction analyses were conducted to assess the dam’s performance under static and dynamic conditions.

Causes of Tensile Strain of Asphalt Concrete Core Wall of Rockfill Dam in High‐Cold Area During Construction

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
Asphalt concrete core rockfill dams, favored for their superior impermeability and adaptable deformation capacity (effectively accommodating uneven settlement), have been gaining increasing attention in Chinese engineering practice. However, ensuring safety during high‐temperature paving and subsequent cooling remains crucial.

Feedback Analysis of Deformation Modulus for an Extra‐High Arch Dam With Dam Height of 300 m Level

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
Deformation is a critical indicator for safety monitoring of arch dams in operation; comparing measured deformation values with calculated ones is a common approach to assess dam behavior. However, deformation calculated based on design deformation parameters often significantly differs from measured values, especially for extra‐high arch dams; to ...

Geotechnical analysis of Beliche dam [PDF]

, 2003
Beliche Dam is an earth dam located in the southeast of Portugal, in the Algarve province. It was built between 1982 and 1985, over a ground composed of sands and gravels coming from the Beliche River, a tributary of the Guadiana River.

Coupling sPCA‐Based Statistical Modeling With Deep Residual Networks Considering Thermal Effect for Deformation Forecasting in High Dams

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
Accurate prediction of deformation under thermal influences is critical for the safety assessment and long‐term performance of high dams. This study proposes a novel two‐stage prediction framework that integrates statistical modeling with deep learning to enhance the interpretability and accuracy of dam deformation forecasting.

The Hydraulics of Stepped Chutes and Spillways [PDF]

, 2002
The stepped channel design have been used for more than 3,500 years (chapter 2). A significant number of dams were built with overflow stepped spillways during the 19th century and early 20th century, before the design technique became outdated with the ...

Altered flow and sediment transport impacts on the ecosystems of Chinese major rivers: An urgent call for eco‐fluvial dynamics

River, Volume 3, Issue 4, Page 341-361, November 2024.
Abstract River ecosystems face challenges due to environmental degradation and alterations in flow and sediment transport resulting from climate change and other anthropogenic impacts. These changes may substantially affect river morphology, nutrient dynamics, wetland vegetation, aquatic habitats, and river ecological stability.
