摘　　要：以实际桥梁工程引桥为例,介绍花瓶墩的设计与计算过程,并根据花瓶墩的受力特点,着重对这种类型桥墩的横桥向应力进行详细的计算和分析,结果表明,墩顶横桥向拉应力较大,需加强配筋;桥墩剪应力较小,仅需按构造配筋。Taking practical bridge approach engineering for instance, the paper introduces the design and calculation process of vase piers, and emphasizes the detailed calculation and analyzes the stress of this type of piers in transverse direction of bridge according to the stress characteristics of vase piers. The analysis results show that the tensile stress in the top of piers in transverse direction of bridge is great, the reinforcement should be strengthened. What＇s more, its shearing strength in piers is less, so the reinforcement should be done according to conformation.

关 键 词：花瓶墩 横桥向 拉应力 剪应力
