To compare the stability of rockfill dams with vertical and inclined clay cores, focusing on seepage and safety factors.
Conducted slope and seepage stability analysis of a rockfill dam
Compared vertical and inclined clay core geometries
Used numerical modeling software GEO-Studio 2012
Performed analysis under static loading conditions
Flux through the inclined clay core dam is 0.0057 m³/sec compared to 0.0073 m³/sec for the vertical core
Safety factors for the inclined core were found to be acceptable based on allowable limits
The inclined clay core was identified as more economical than the vertical clay core
