Abstract
Thedynamicresponsesofstructuresunderblastloadingaremuchmorecomplicatedthan
thoseunderotherloadingssuchasstaticandearthquakeloadings.Inordertofullyrealizetheblastresistancesofconcretegravitydams,
agreatmanynumericalsimulationswereimplementedbyusing
three-dimensionalnonlinearfiniteelementmodels.Theinfluencesofdamheightandwaterlevelbeforethedamsontheblastresistanceofthedamswereanalyzed,
andatheoreticalbasiswasprovided
forantiknockperformanceevaluationandprotectiondesign.Strainrateeffectsofconcretedamswere
takenintoconsiderationintheestablishmentofthefully-coupledmodelforthegravitydams.Forthis
kindofconcretegravitydams,numericalresultsindicatethattheblastresistanceofthelowdamsis
weakerthanthatofthehighdams,thatthewaterlevelbeforethedamsplaysanimportantroleonthe
antiknockperformancesofthedams,andthattheantiknockperformancesofthedamscanbeeffectivelyimprovedbyreducingthewaterlevel.
