This　research　mainly　focuses　on　reinforcement　design　scheme　of　Chongdong　double　curve　arch　bridge.　Based　on　local　survey　and　detecting　experiment,　finite　element　software　was　used　to　establish　FEM　model　and　calculating　the　real　working　state　of　bridge.　After　extensive　analysis　of　bridge　defects,　reinforcement　scheme　was　designed.　Coating　of　glue　carbon　fabric　at　mid　portion　of　main　and　side　span,　glue　steel　plate　at　the　central　main　arch　rib　and　the　spandrel　column　were　designed　to　be　rehabilitated　with　steel　plate　cover.　Further,　10　cm　thick　concrete　at　springing　of　arch　was　recommended.　On　top　of　that,　spandrel　arch　was　designed　to　rehabilitate　with　RC　concrete　and　rebuilt　for　pavement　is　strongly　recommended.　The　rehabilitated　bridge　meets　the　normal　working　condition　and　the　limiting　serviceability　condition.　It　is　concluded　that　after　the　Chongdong　double　curve　arch　bridge　are　reinforced,　the　bridge　structure　bearing　capacity　is　much　enhanced,　which　shows　big　strength　and　stiffness,　the　bearing　capacity　and　work　state　meet　the　design　and　use　requirement.
