摘　　要：针对合阳嘉陵江大桥桥墩及拱圈形状结构 ,通过水槽实验 ,建立了在不同桥墩形状、桥墩数目、淹没水深、水流与桥轴线法向夹角等影响因素综合作用下 ,桥梁局部阻力系数公式 .In accordance with the date obtained from the expriment of the model which refers the form of bridge column,arch block and spandrel structure,angle between master stream and normal direction of the axis of Heyang Bridge above the Jialingjiang River,a formula of coefficient of local resistance contained the parameter of dimensions,number,submerging hight,etc.of the column is established in this paper.The formula can be for referrence before calculating of the rising surface curve of similar bridges.

关 键 词：桥墩 合阳嘉陵江大桥 局部阻力系数 壅水曲线 桥梁设计 拱圈 通航问题
