Abstract：

In　this　study,　numerical　simulations　of　wind　fields　at　bridge　locations　in　complex　terrain　are　conducted　with　utilization　of　Fluent.　Terrain　modeling　was　performed　based　on　the　GIS　data,　wind　characteristics　and　the　ground　roughness　coefficient　are　obtained　by　numerical　simulation　different　wind　directions.　the　acceleration　effect　of　the　terrain　on　the　wind　field　under　different　working　conditions　are　explored.　Results　show　that　the　wind　speed　ratio　of　the　bridge　site　area　is　1.38　and　the　minimum　value　is　0.84,　which　may　provide　references　for　the　wind　resistance　design　of　the　large　span　bridges.　©　Published　under　licence　by　IOP　Publishing　Ltd.
