Advances in Civil Engineering, Volume 2026, Issue 1, 2026.The antiseepage curtain is one of the main antiseepage measures for asphalt concrete core rockfill dams. Taking Huanglong Pumped Storage Power Station as an example, this study established a three‐dimensional seepage model including the dam and the dam foundation antiseepage curtain.

Dynamic deformation characteristics of sands and rockfill materials
, 1993 Cyclic torsional simple shear (CTSS) tests and cyclic triaxial (CTX) tests were carried out to investigate the dynamic deformation characteristics of sands and rockfill materials. It was found that the shear modulus and damping ratio can be expressed as

Modeling Static Behavior of Rockfill Materials Based on Generalized Plasticity Model
Advances in Civil Engineering, 2019 Rockfill materials are commonly used for dam construction. Establishing an effective model that can reasonably describe the mechanical properties of rockfill material is very important for the calculation of earth-rock dam engineering.

The Spatial Gradation Characteristics and Intensity Evolution Law of Mine Dump
Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Most of the mine dumps have very prominent slope stability problems. In this paper, by analyzing the gradation characteristics and spatial distribution characteristics of the discharged particles, the functional relationship between the characteristic particle size parameters and the relative height of the dump was obtained.

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.This study investigates the macro‐meso mechanical evolution of dam rockfill under the coupled effects of coarse‐particle content (P5) and confining pressure (σ3) using large‐scale triaxial tests and PFC3D simulations. The results show (1) shear strength and particle breakage depend synergistically on σ3 and P5.

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

Aquaculture Research, Volume 2026, Issue 1, 2026.Mark‐recapture studies using fluorochrome dyes are a valuable approach for validating the age determination of fish, yet the optimal chemical marker and its dosage for adult European flounder (Platichthys flesus Linnaeus, 1758) remain unclear. We assessed the effectiveness of tetracycline hydrochloride and calcein at different concentrations for ...
