Combinated seepage failure tests on cushion and transition materials for Cihaxia Hydropower Station

open access: yesYantu gongcheng xuebao
For the ultra-high concrete face rockfill dams, natural sand and gravel materials are used as the dam materials for rockfill dam projects. The combined impermeability stability of the dam partition materials is very important to the dam safety.

Breaching of Rockfill Dams

open access: yes, 2020
Destructive breakout floods that are generated by the breaching of embankments need to be assessed in the risk evaluation of potential hazards to prepare emergency action plans. The current standard practice to assess the breaching of embankment dam is with statistically derived parametric equations based on historic dam failures.
