摘要
以三股线高架桥为例，简述了利用ANSYS软件的模态和瞬态分析功能对高墩T构-连续梁桥的振动特性和动力反应进行了仿真分析的过程，探讨了不同车型以：不同车速过桥时高墩T构-连续梁桥冲击系数的变化规律，并通过现场实际结构动力特性的测试分析结果，对计算机仿真结果的精度进行了验证．为该类桥型的动力分析提供借鉴．
Using the SanGuxian continuous - structure girder bridge as an example, this paperdemonstrated how the mode and transient analysis function of ANSYS software can be used to analyze the dynamic characteristics of the high pier T - type rigid framecontinuous bridge, investigating how the impact coefficient of T - type rigid framecontinuous bridge changes as vehicles pass at different speed. Through dynamic teston the spot, the precision of the result was testified. This paper offers referencefor the analysis of the dynamic characteristics of bridges of the same type.
