It　is　very　significant　to　carry　out　the　qualitative　and　quantitative　research　on　the　dynamic　properties　of　grouting-reinforced　rock　mass,　which　directly　reflects　the　grouting　reinforcement　effect　of　broken　rock　mass　and　its　dynamic　stability　in　engineering.　By　selecting　typical　fragments　and　simplifying　the　simulation　of　grouting　process,　the　grouting-reinforced　rock　mass　was　prepared　using　a　core　machine.　In　the　process,　the　uniformity　of　rock　crack　was　promised　and　randomness　of　the　grout　diffusion　was　neglected.　Dynamic　shock　tests　of　the　grouting-reinforced　rock　mass　was　carried　out　by　using　the　Split　Hopkinson　Pressure　Bar.　The　results　show　that,　the　quality　ratio　between　the　rock　mass　and　cement　plays　an　important　role　on　the　dynamic　properties　of　grouting-reinforced　rock　mass,　and　the　peak　strength　can　reach　the　maximum　under　an　optimal　ratio.　In　addition,　based　on　the　continuum　damage　theory　and　statistical　strength　theory,　a　dynamic　damage　mechanics　model　for　grouting-reinforced　rock　mass　was　presented,　and　the　model　parameters　were　fitted,　which　have　a　great　association　with　the　sample　components.　There　is　a　good　coherence　between　stress-strain　curves　calculated　by　the　proposed　model　and　those　obtained　directly　from　the　experimental　data.　The　research　results　may　extend　the　theoretical　study　fields　with　respect　to　the　properties　of　grouting-reinforced　rock　mass.　©　2017,　Editorial　Office　of　Journal　of　Vibration　and　Shock.　All　right　reserved.
