| 摘 要： | 利用大型有限元程序，对某一连续刚构桥进行了地震响应敏感性参数分析。基于正交试验，采用地震时程分析法研究了桥梁跨数和墩高、行波波速、桩土作用、地震波类型等参数对连续刚构桥地震响应的影响。发现不同的反应值，如最大弯矩和最大位移对应了不同的敏感性参数。在所考虑的因素中，墩高和桩土作用对连续刚构桥的地震响应影响较大。

| Abstract: | The sensitive parameters to earthquake response of a continuous rigid frame bridge, the number of the spans of the bridge, the height of the pier, travelling wave velocity, soil-structure interaction and the type of seismic wave, are analyzed using the finite element method based on cross test technique. The result shows that different response values of the bridge to an earthquake, such as maximum moment and maximum displacement, are sensitive to different parameters respectively, and the values vary greatly due to the changes of pier height and soilstructure interaction. |
