深水高墩桥梁的地震响应分析
|
摘要
通过对Morison方程和各种规范规定的动水计算方法的比较,最后选择在Morison方程的基础上,用附加质量考虑水的影响,计算深水桥墩的地震响应,得出矩形深水墩动水作用下桥梁地震反应,为进一步分析墩体遭地震破坏形式及破坏程度提供可靠数据保证。
According to the comparison between Morison equation and the dynamic water calculation methods of all regulations,the paper has the selection based on Morison equation,adopts the additional quality to consider the water's influence,calculates the earthquake response for the deepwater bridge pier,concludes the earthquake response of the bridge under the effect of the rectangular deepwater pier dynamic water,so as to provide the reliable data guarantee for the further analysis of the damage forms and damage degrees of the piers caused by the earthquake.
