    Abstract
  • ByusingasplitHopkinsonpressurebarsystem,thedamageeffectsofporoussandstone specimenswereexperimentallyinvestigatedbyconsideringfluid-solidcoupling.Thedynamicstressstraincurvesoftheporoussandstonespecimenswereobtainedundertherepeatedimpactloadings withdifferentspeedsandtheiracousticwavespeedsweremeasuredbeforeandafterimpact.Thedamageresultsofthesandstonespecimenswereanalyzedandthemaininfluencingfactorswereexplored. Thevaryingcurvesofthebreakingstrengthsofthesandstonewereobtained withacousticwave speedsandporousratio,respectively.Andtheinfluencesofporosityandcouplingmediawereproposedontheimpactdamageeffectsofporoussandstone.
