| 摘 要： | 桩-土-结构动力相互作用使桥梁结构的动力特性、阻尼和地震反应发生改变,而忽略这种改变有时是偏危险的。因此,在进行桥梁的地震反应分析时,应考虑桩-土-结构的相互作用。文中借助Midas有限元分析软件,采用反应谱法对考虑桩-土作用与不考虑桩-土作用作了详细的地震反应计算分析,通过对两种计算结果的比较,分析了考虑桩-土作用与不考虑桩-土作用连续刚构的内力与位移。

| Abstract: | The interactions of the pile-soil-structure make some changes in the dynamic characteristic and damp,including the effect of earthquake in the structure of bridge,but ignoring the changes may bring some dangers.We should consider the interactions while we analyze the action of earthquake in structure of bridge.We in detail calculate the actions of the earthquake both considering the effects of pile-soil and un-considering the effects of pile-soil using the method of response spectrum,with the help of Midas finite element analysis software.The internal force and displacement of the continuous rigid frame are analyzed in considering the action of pile-soil and un-considering the action of pile-soil by the comparisons of the two results |
