摘要
利用有限元软件Midas/Civil对双肢薄壁高墩连续刚构桥的最大悬臂状态和成桥运营状态进行稳定分析,并考虑日照温差和施工过程中的不平衡荷载以及静风荷载的影响,讨论墩间系梁道数及系梁位置对双肢薄壁高墩稳定性的影响。
With the finite element analysis software MIDAS/CIVIL, the stability of the continuous rigid structure bridge with double-shaft and thin-wall high-rise piers under the longest cantilever construction and after-completion performance have been analyzed, with taking into account the effect of sunlight temperature difference, lopsided load during construction and static wind load. The influence to the stability of the double-shaft and thin-wall high-rise pier by the number and position of collar tie beams has been discussed.
