摘　　要：结合某山区高墩大跨连续刚构桥的动力特性分析,研究了钢—混凝土组合格构柱高墩连续刚构桥的动力特性分析方法,探讨了该类桥梁的动力特性结构行为及规律;在一定参数的基础上,研究了墩高、边界约束条件、曲线形式、曲线半径和横向连接系等参数的影响。计算结果为该类桥梁的抗风、抗震设计研究提供了分析基础。With analysis of dynamic characteristics of the long-span rigid frame bridges with high piers which is located in mountains,method for analysis of dynamic characteristics of the long-span rigid frame bridges is researched,and structure behavior and law of dynamic characteristics of this type of bridge are studied.On structural dynamic property,the important effects of the structural parameters,such as pier height,boundary condition,curved-girder section of the bridge and transverse connection,is studied.Some useful results about this type of bridge is made for seismic and wind resistance design.
