改扩建高速公路门架墩结构计算分析

摘要

通过对某改扩建高速公路门架墩结构的有限元计算分析,总结了其结构受力特点,并对考虑和不考虑桩基参与受力两种情况下的门架墩计算结果进行了探讨,进而得出了一些有指导意义的结论。%Through the finite element calculation analysis on a portal frame pier structure of expressway reconstruction and extension,this paper summarized the force characteristics of this structure,and discussed the calculation results of portal frame pier under considering and not considering pile foundation in force two situations,and then gained some instructive conclusions.
