Concrete　arch　bridge　has　the　advantages　of　beautiful　shape,　good　overall　performance,　large　crossing　distance,　excellent　durability　and　low　economic　cost.　However,　some　problems　still　exist　such　as　excessive　arch　ring　weight,　low　bearing　efficiency,　difficult　concrete　webs　pouring　and　long　construction　period.　In　order　to　solve　the　above　problems　of　concrete　arch　bridge,　the　concept　of　concrete　arch　bridge　with　UHPC　butterfly　webs　is　proposed.　Based　on　Wumeng　Mountain　Bridge　with　concrete　arch　bridge　with　UHPC　butterfly　webs,　the　trial　design　of　this　new　type　of　bridge　is　carried　out.　The　results　show　that　static　properties　of　the　new　bridge　type　from　three　aspects　of　arch　ring　strength,　stability　and　deformation　are　checked,　and　all　meet　the　requirements　of　the　code,　UHPC　butterfly　webs　instead　of　steel　truss　webs　have　little　effect　on　the　dynamic　characteristics　of　arch　bridge.　The　new　bridge　type　has　the　characteristics　of　significantly　reducing　the　self-weight　of　concrete　arch　bridge,　high　bearing　efficiency,　and　more　mature　and　relatively　simple　construction　methods.　New　bridge　type　can　meet　the　design　requirements.　©　The　Author(s),　under　exclusive　license　to　Springer　Nature　Switzerland　AG　2025.
