Seismic Safety of Rockfill Dam with Asphalt Concrete Core on Overburden Layer
Renmin Zhujiang, 2023 As the rockfill dam with an asphalt concrete core is built over the thick overburden layer,the overburden layer affects the dynamic response of the dam and aggravates the whiplash effect.Cutoff structures are also affected,especially the cutoff wall of ...

Investigation for the Key Technologies of Ultra-High Asphalt Concrete Core Rockfill Dams
Soils and Foundations, 2019 Abstract The mechanical characteristics of ultra-high asphalt concrete core rockfill dams (UACCRDs) at different periods is investigated via Rankine’s earth pressure theory, and a shear safety control standard for UACCRDs is proposed. The reasonable material parameters of the asphalt concrete core (ACC) and transition material that independently and ...
