摘要
为分析特殊的"T"形托盘式顶帽在荷载作用下应力分布的特征及布筋特点,结合茂湛铁路石门特大桥实例,采用空间有限元分析软件MIDAS/Civil建立了三维实体模型,分析了该托帽强剪弱弯特性的应力分布情况,并总结了其布筋要点,以保证托盘式顶帽的正常工作。
This paper established three-dimensional solid model of the T-bulk-head pier which is applied in Shimen grand bridge of Mao-Zhan railway by finite element analysis software MIDAS / Civil and analyses the stress under load. The results show that the characteristics of strong shear weak bending and stress distribution in T-bulk-head pier is feasible to ensure the structure normal operation.
