设计了一种用于节段拼装桥墩的弯曲螺栓连接构造，采用数值模拟方法对带连接桥墩和常规桥墩进行对比分析，结果表明：与常规桥墩相比，拼装桥墩初始刚度和破坏形态不变，极限侧向力承载能力下降很少，设计方案可行。%A kind of connecting using curved bolt for modular pier is designed in this paper. By using numerical simulation methods the perform-ance of modular pier and conventional pier is compared. The results showed that:compared with the conventional pier,initial stiffness and failure pattern of modular pier is unchanged,lateral force resistance decreased only a little. The design is feasible.
