Numerical Simulation of a 3D Seepage Field of an Asphaltic and Concrete Core Rockfill Dam in an Arid Area

open access: yesGeofluids, Volume 2022, Issue 1, 2022., 2022
This investigation focused on the three‐dimensional (3D) seepage field simulation of an asphaltic concrete core rockfill dam (ACRD) under the design water level conditions. At first, the finite element theory of seepage is introduced in the arid area; then, a hydro‐junction projection on the Nuer River in Xinjiang is selected as engineering background,
