Compressive Behavior of Hydraulic Asphalt Concrete under Different Temperatures and Strain Rates
Publisher: ASCE
Abstract: Hydraulic asphalt concrete (HAC) used as upstream facing of embankment dams is subjected to different temperatures and loading conditions. The main goal of this paper is to investigate the compressive behavior of HAC under ...
Experimental Study on Effect of Temperature on Direct Tensile Behavior of Hydraulic Asphalt Concrete at Different Strain Rates
Publisher: ASCE
Abstract: The tensile mechanical properties of hydraulic asphalt concrete (HAC) play a significantly important role in the safety of the impervious core in embankment dams. This paper aims to develop a direct tensile test setup with ...
Seismic Response of Embankment Dams with Asphalt–Concrete Cores Based on the Three-Dimensional Time-Domain Inversion of Ground Motions
Publisher: ASCE
Abstract: In this paper, the three-dimensional time-domain inversion of ground motions and its application are performed. The relationship between the incident wave time series and design ground motions is established, and the oblique ...
Effect of Valley Topography on the Behavior of Asphalt Concrete Core Walls in Earthen Dams
Publisher: American Society of Civil Engineers
Abstract: An increasing number of asphalt concrete core wall earthen dams (ACCDs) are being constructed under complex topographical conditions. The narrow or asymmetrical river valleys might lead to significant arching effects and ...
Comprehensive Evaluation Method for the Concrete-Face Rockfill Dams Behavior Based on the Fuzzy Recognition Model
Publisher: ASCE
Abstract: Concrete-face rockfill dams (CFRDs) usually face different safety problems, such as dam cracks caused by uneven deformation, face slab cracking, dam slope instability, and excessive leakage, during their long-term operation. ...
Predicting the Crest Settlement of Concrete Face Rockfill Dams by Combining Threshold Regression and Support Vector Machine
Publisher: ASCE
Abstract: The design and construction of concrete face rockfill dams (CFRDs) usually require a rapid and accurate prediction of deformation behavior to support dam optimal design and safety evaluation. Deformation prediction and ...
Optimization of the Joint Structure Between Asphalt Concrete Core and Concrete Plinth in Earthen Dams Based on the Response Surface Method
Publisher: American Society of Civil Engineers
Abstract: The joint structure between the asphalt concrete core and the concrete plinth is a critical and vulnerable part of the asphalt concrete core dam (ACCD). Shape parameters of the core–plinth joint structure are directly ...
Quantitative Study on the Influence of Alluvium Foundation on the Behavior of Concrete Face Rockfill Dam
Publisher: ASCE
Abstract: An increasing number of concrete faces rockfill dams (CFRDs) are being built on deep alluvium foundations. Understanding the behavior of CFRDs that are built on alluvial foundations is critical to the performance assessment ...
