A model for the analysis of the structural failure of the clay core in rockfill dams due to overtopping
MetadataShow full item record
In 2014 the Dam Safety Research Group (SERPA) of the Technical University of Madrid performed several tests to assess the behavior of rockfill dams in overtopping scenarios. A structural failure pattern of the clay core was observed, as expected. Hence, it was concluded that a model to simulate the observed failure mechanisms was needed. The model described herein provides the first results on assessment of the clay core stability following failure of the downstream shell. The failure process may result in one or more brittle and abrupt breakage phases of the core, herein classified as structural ...
