高桥墩刚度对桥梁抗震特性的影响研究

Research on influence of high bridge pier rigidity to bridge earthquake resistance

针对3种不同桥墩型式研究了桥墩刚度变化对全桥抗震特性的影响,并通过工程实例进行分析比较,提出了桥梁高墩在选择上应注意的问题。

Based on three kinds of different bridge pier patterns,this article has studied the influence of the bridge pier rigidity＇s changes to the entire bridge earthquake resistance,and carries on the comparative analysis through the engineering example,the author proposed the question to which high bridge pier should be paid attention in the choice.
