Abstract

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