摘　　要：V形墩连续刚构桥结构力学状态复杂多变,结构参数较大。为研究V形桥墩连续刚构桥设计参数对结构力学性能的影响,本文以某V形桥墩连续刚构桥为工程背景,基于控制变量法原则,研究了V形墩连续刚构桥不同的边中跨比μ、V腿角度α、中墩约束刚度K等设计参数对结构支反力和内力的影响。研究表明,不同结构参数对桥梁的支反力和内力具有显著影响,其结果对于设计人员从整体把握V形墩连续刚构桥的力学行为、高效地进行总体设计具有积极意义。This paper is based on Huzhonglu Bridge,V-shape pier continuous rigid frame bridge crossing Paihonggang River,in Zhangzhou City and researches influences of support reaction and internal force of structure under different ratio of side-span and mid-span,angle of V-legs,restraint stiffness of middle pier.The research shows that the different structural parameters have a significant impact on support reaction and internal force.So,the results have a positive meaning on mastering the mechanical behavior of V-shape pier continuous rigid frame bridge for bridge designers which are conducive to making overall design efficiently.
