Abstract：

In　mountain　road　construction,　strand　anchors　face　rapid　axial　impacts　from　blasting　slope　excavations,　necessitating　high　impact　resistance　for　structural　stability　and　durability.　CFRP　(Carbon　Fiber　Reinforced　Polymer)　strand　anchors　have　more　complex　impact　damage　mechanisms　than　metal　ones,　influenced　by　various　factors.　In　this　study,　impact　resistance　tests　were　conducted　on　15.2　mm　diameter　CFRP　and　steel　strand　anchors.　The　results　indicate　the　impact　resistance　of　CFRP　is　approximately　15　%　of　that　of　steel　strand　anchors　with　the　same　diameter.　The　elongation　caused　by　the　impact　is　only　14　%　of　that　under　static　load.　A　predictive　formula　for　the　maximum　impact　force　of　CFRP　strand　anchors　under　impact　was　developed,　with　experimental　validation　demonstrating　an　error　margin　of　less　than　5　%　between　theoretical　and　measured　values.　©　2024　The　Author(s)
