摘要
通过对内昆线花土坡特大桥空心高墩进行地震反应分析,研究了墩顶约束作用、墩底弹簧约束、P-Δ效应对地震反应的影响,得出了一些关于铁路空心高墩地震反应方面的有意义的结论.
In this paper, seismic response of a railway hollow high pier is analyzed. The effects on seismic response of the constraint on the top,the spring at the bottom and P-Δ are researched. Some meaningful conclusions on the dynamic behavior of hollow high pier are drawn.
