The　dynamic　spalling　characteristics　of　rock　are　important　for　stability　analysis　in　rock　engineering.　This　paper　presented　an　experimental　investigation　on　the　dynamic　spalling　characteristics　of　granite　with　different　temperatures　and　strain　rates.　A　series　of　dynamic　spalling　tests　with　different　impact　velocities　were　conducted　on　thermally　treated　granite　at　different　temperatures.　The　dynamic　spalling　strengths　of　granite　with　different　temperatures　and　strain　rates　were　determined.　A　model　was　proposed　to　correlate　the　dynamic　spalling　strength　of　granite,　high　temperature　and　strain　rate.　The　results　show　that　the　spalling　strength　of　granite　decreases　with　increasing　temperature.　Moreover,　the　spalling　strength　of　granite　with　a　higher　strain　rate　is　larger　than　that　with　a　lower　strain　rate.　The　proposed　model　can　describe　the　relationship　among　dynamic　spalling　strength　of　granite,　high　temperature　and　strain　rate.　©　2023　Institute　of　Rock　and　Soil　Mechanics,　Chinese　Academy　of　Sciences
