摘　　要：衡阳县灵瑞寺(清江)大桥北起蒸阳大道,向南跨越滨江路、蒸水河和英南新区规划的滨河路,终点与英南新区规划的新城路连接,主桥采用四肢中承式异形提篮系杆拱桥。针对衡阳县地处五岭上升和洞庭湖下陷的过渡地带,桥梁设计根据组合琴拱桥理论,合理调整拱轴线,改变拱肋截面大小,拱圈灌注混凝土,主梁采用大悬臂波形钢腹板-桁架组合结构等措施,减小拱脚水平推力、节省水平系杆;充分发挥组合材料的力学性能,增加拱肋刚度,增强主拱横向稳定性;提高截面的结构效率,有效减轻桥梁自重,提高桥梁结构耐久性。The northern of Hengyang Lingrui temple（Qingjiang）bridge is located in Zhengyang Avenue and across Binjiang Road,Zhengshui River and Binghe Road of new district planning southward,the end connect to Xincheng road of Yingnan new district planning,main bridge is four-support midheight deck basket-handle-tied-arch bridge.Based on the transitional zone between the rising area of Five Ridges and fallen area of Dongting Lake,according to the theory of combination piano arch bridge,reasonable adjustment of arch axis could change the arch rib section size,as well as pouring concrete of arch ring,large cantilever corrugated steel web-truss composite structures was applied in main girder.As a result,the horizontal thrust of arch foot and horizontal tie bar were reduced,and gave full play to the mechanical properties of composite materials,so as to increase the arch rib rigidity and lateral stability of the main arch.The efficiency of the structure of the cross section and the durability of bridge structure were improved,the weight of the bridge was reduced.
