To　resolve　the　problem　of　heavy　self-weight,　easy　cracking　and　low　load-bearing　capacity　of　ordinary　concrete　poles,　on　the　basis　of　centrifugal　molding　process,　the　optimal　mix　ratio　of　coarse　aggregate　UHPC　was　designed　by　adjusting　the　centrifugal　speed,　acceleration　and　time.　Six　UHPC　annular　poles　with　coarse　aggregate　were　made　by　variable　speed　centrifuge,　thus　enhancing　the　production　efficiency.　The　failure　mode,　crack　resistance　and　bearing　capacity　were　investigated　by　four-point　bending　static　loading　with　steel　fiber　content　and　reinforcement　ratio　as　parameters.　The　test　results　show　that　the　failure　mode　of　the　pole　can　be　divided　into　three　stages:　elasticity,　crack　development　and　failure.　With　the　increase　of　steel　fiber　content,　the　number　of　main　cracks　of　the　pole　gradually　decreases,　while　the　number　of　minor　cracks　increases　accordingly.　Steel　fiber　hindered　the　development　of　cracks　to　a　certain　extent,　and　its　flexural　capacity　increased　by　42.　6%　.　With　the　increase　of　reinforcement　ratio,　the　number　of　main　cracks　of　the　pole　is　not　much　different,　but　the　length　and　width　of　the　cracks　are　obviously　reduced.　The　resistance　to　deformation　is　strengthened,　and　the　flexural　bearing　capacity　is　increased　by　63.　8%　.　The　calculation　results　of　flexural　bearing　capacity　of　RPC　pole　is　close　to　the　experimental　value,　but　relatively　safe　and　conservative.　However,　with　the　increase　of　reinforcement　ratio　and　steel　fiber　content,　the　theoretical　calculation　value　is　closer　to　the　experimental　value.　The　calculation　method　of　the　flexural　bearing　capacity　of　the　activated　powder　concrete　pole　is　similar　to　that　of　the　test　results.　©　2023　Harbin　Institute　of　Technology.　All　rights　reserved.
