Long-term deformation characteristics of high concrete-faced rockfill dams under cyclic loading of water

Yantu gongcheng xuebao
The long-term deformation of high concrete-faced rockfill dams is one of the key technical problems during their construction. Most studies have attributed the long-term deformation to rockfill creep, but the prototype monitoring data of some high ...

Experimental study on filling standard of high rockfill dams with soil core

Yantu gongcheng xuebao, 2019
The monitoring data of high ECRDs have shown that the deformation coordination in dam material zones does not meet the design goal, which is related to the degree of matching in the current specifications of filling for the filtration zone, transition ...

Breaching of Rockfill Dams

, 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.
