| 摘 要： | 以水南特大桥主桥为研究对象,利用大型通用有限元程序MIDAS/Civil建立了该桥桥墩0号块的空间有限元计算模型,对0号块在施工阶段及成桥运营阶段两种工况下的应力进行了分析.计算结果表明,该桥桥墩0号块除在横隔板人孔部位略为薄弱外,其余部位均满足规范要求,计算结果已为该桥设计提供依据,对同类桥梁0号块设计也具有一定的参考价值.

| Abstract: | Due to the extreme complexity of segment No.0 for the prestressed concrete continued rigid frame bridge,it is necessary that the spatial analysis of segment No.0 on the piers be made in practice.In this paper the Shuinan super large bridge is studied.The finite element analysis program MIDAS/Civil is applied to set up a three-dimensional solid finite element computational model of segment No.0 to calculate the stress of it when it is under construction and after its completion.The results show that the stress of segment No.0 are in good agreement with the current codes except the manhole part of the diaphragm.The results in this paper have been used for the design for the bridge and can be of great benefit for the similar projects. |
