波形钢腹板PC组合箱梁适用于不同结构形式的桥梁，相比普通混凝土箱梁具有显著的耐久性和经济性，波形钢腹板斜拉桥将波形钢腹板组合箱梁应用到斜拉桥中，充分发挥了2种结构的特点。南昌朝阳大桥主桥通航孔桥为（79＋5×150＋79） m波形钢腹板PC组合箱梁六塔连续单索面斜拉桥，上层布置双向8车道，下层布置人行和非机动车道。通过分析研究，该桥选择了较小的跨中比；由于塔数多，由中塔到边塔传递路径长，边跨设置辅助墩效应小，因此未设辅助墩。采用塔梁固结、梁墩分离的结构体系，箱梁宽43．84 m ，设置钢横隔板；斜拉索为单索面，扇形布置。桥塔外形呈“合”字形，桥塔处设置双支座。采用拉索减震支座作为上部结构的减隔震装置，布置在2个边塔下方。
波形鋼腹闆PC組閤箱樑適用于不同結構形式的橋樑，相比普通混凝土箱樑具有顯著的耐久性和經濟性，波形鋼腹闆斜拉橋將波形鋼腹闆組閤箱樑應用到斜拉橋中，充分髮揮瞭2種結構的特點。南昌朝暘大橋主橋通航孔橋為（79＋5×150＋79） m波形鋼腹闆PC組閤箱樑六塔連續單索麵斜拉橋，上層佈置雙嚮8車道，下層佈置人行和非機動車道。通過分析研究，該橋選擇瞭較小的跨中比；由于塔數多，由中塔到邊塔傳遞路徑長，邊跨設置輔助墩效應小，因此未設輔助墩。採用塔樑固結、樑墩分離的結構體繫，箱樑寬43．84 m ，設置鋼橫隔闆；斜拉索為單索麵，扇形佈置。橋塔外形呈“閤”字形，橋塔處設置雙支座。採用拉索減震支座作為上部結構的減隔震裝置，佈置在2箇邊塔下方。

The PC composite box girder with corrugated steel webs is applicable to bridges with a variety of structural types ,which exhibits superior durability and economic features as com‐pared with the common concrete box girder .The cable‐stayed bridge with corrugated steel webs is regarded as the type of structure where composite box girder with corrugated steel webs is ingen‐iously used ,making better use of the properties of the two structures . The main navigational bridge of the Chaoyang Bridge in Nanchang is a (79+ 5 × 150+79) m continuous composite box girder cable‐stayed bridge with corrugated steel webs .The bridge has six pylons and the stay ca‐bles are arranged in single cable plane .In addition ,the bridge has two layers of decks ,on the up‐per deck ,dual eight vehicle lanes (four lanes each side) are arranged and pedestrian and non‐mo‐torized vehicle lanes are arranged on the lower deck .Based on the analysis and study undertaken , small side span‐to‐main span ratio was chosen .Due to the multiple pylons ,the load path from the intermediate pylons to the side pylons is long and the effect of ancillary piers in the side spans is minimal ,as a result ,no ancillary piers are installed .In the structural system ,the pylons and the main girder are fixed while the girder and piers are separated .The box girder is 43 .84 m wide , with transverse steel diaphragms .The stay cables are fanned out in single cable plane .The pylon looks like the Chinese character“合“ ,and double bearings are installed at the pylons .T he stay vi‐bration mitigation bearings are used as the vibration mitigation and isolation devices of the super‐structure ,which are installed below the two side pylons .
