摘要
根据圣维南原理采用Midas FEA有限元分析软件对某主跨为140 m的大跨径连续刚构梁桥的0号块进行了空间应力分析,分析工况取施工最大悬臂阶段及成桥运营阶段受力最不利状态,计算结果表明该桥满足施工期间及运营期间规范允许值,计算结果为设计提供一定依据,对同类桥梁0号块设计具有一定参考价值。
According to the Saint-Venant's Principle, using Midas FEA finite element analysis software,this paper analyzed the space stress of 0 block for a mainspan of 140 meters long span continuous rigid frame bridge. It also analyzed the working condition and took the most unfavorable condition in the construction largest cantilever stage and a bridge operation stage. The calculation results showed that the bridge met the specification allowable values during the construction and operation period, which provided the basis for design and had a certain reference value for the similar bridge 0 block design.
