Unsaturated Wetting Deformation Characteristics of a Granite Rockfill under Rainfall Conditions

, 2022
Rainfall-induced unsaturated wetting deformation has been one of the main sources of post-construction deformations of rockfill structures. An experimental study is presented of the unsaturated wetting deformation characteristics of a weakly-weathered ...

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

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

Numerical simulation of size effect on shear strength and deformation behavior of rockfill materials

Yantu gongcheng xuebao, 2018
The scale effect of rockfill materials is crucial to predicting the strength and deformation of earth-rockfill dams. Due to their large particle size and the experimental restrictions, large triaxial tests on full scale samples are seldom conducted.

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.

Field Experimental Study on Dynamic Response of Soft Foundation During Dynamic Compaction Replacement Construction

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
To investigate the dynamic response of soft soil foundation, field tests were conducted on a highway project in the mountainous area of Guizhou, where the dynamic replacement (DR) method was applied for foundation improvement. The evolution of excess pore water pressure and ground acceleration response during the compaction process was studied.

Gradation evolution model based on particle breakage characteristics for rockfill materials

Yantu gongcheng xuebao, 2019
Particle crushing will change the density and gradation curves of geotechnical materials, and then influence their stress-strain behavior. The proposed gradation evolution model, based on the particle breakage characteristics of natural rocks, is to ...
