In　geotechnical　engineering,　activities　such　as　landslides,　rockfalls,　blasting,　and　excavation　often　subject　jointed　rock　masses　to　dynamic　shear　loads,　impacting　project　stability.　With　continuous　innovation　of　anchoring　support　technology,　the　appearance　of　energy-absorbing　bolts　has　provided　more　options　for　rock　support.　This　study　selected　fully-grouted　bolts　and　energy-absorbing　bolts,　considering　the　roughness　of　natural　rock　joints.　Indoor　shear　tests　were　conducted　on　bolted　specimens　at　varying　shear　velocities.　A　comprehensive　analysis　was　conducted　on　the　failure　morphology　of　joint　surfaces　and　the　fracture　characteristics　of　bolts.　Subsequently,　the　shear　performance　of　both　bolt　types　was　quantitatively　assessed　through　absorbed　shear　energy.　At　the　interface　between　fully-grouted　bolts　and　joint　surfaces,　stress　concentration　phenomena　were　observed.　In　contrast,　energy-absorbing　bolts　exhibited　significant　necking　phenomena.　Under　external　forces,　the　bolt　body　detached　from　the　grout,　enabling　it　to　accommodate　large　deformations　of　the　rock　mass　and　absorb　energy.　The　results　indicate　that　energy-absorbing　bolts　demonstrate　better　adaptability　and　energy　absorption　capacity　under　high-velocity　shearing,　while　fully-grouted　bolts　exhibit　higher　peak　shear　stresses.　Based　on　the　experimental　findings,　for　projects　requiring　consideration　of　dynamic　shear　loads　and　energy　absorption　capabilities,　energy-absorbing　bolts　may　be　more　suitable,　providing　additional　safety　assurance.　Conversely,　fully-grouted　bolts　may　be　more　appropriate　for　applications　with　higher　requirements　for　shear　resistance,　such　as　structural　support　under　general　static　loads.　©　2024
