| 摘 要： | 对广西桂林雉山混凝土拱桥进行了三维有限元动力学分析，在获取该桥的动力特性后，利角时程分析法计算了桥梁结构的地震反应，通过对位移、加速度、轴力、剪力和弯矩的综合分析，得出在地震作用下该桥拱脚与离拱脚1／4拱处为最危险截面的结论，为拱桥的加固和防震提供了参考和依据．

| Abstract: | Dynamical analysis of the Zhishan concrete arch bridge in Guilin is completed using the finite element model in three dimensions.Based on the dynamical characters of this arch bridge, the reaction of the bridge structure to earthquake is calculated by time-history analysis.Through contrast of displacements, acceleration, axis forces, shear forces and bend moments,the most dangerous section in earthquake is found out and provides references for reinforcement of arch bridges. |
