摘要
运用两步有限元分析法,建立全桥整体空间分析模型,确定拱脚节点的最不利荷载组合效应;建立了拱脚与台座连接区域线性和非线性的精细化有限元分析模型,通过对比研究了三个拱脚过渡段比较方案的局部应力分布规律,提出了合理的构造方案,为同类桥梁的设计和建造提供借鉴。
The two-step finite element analysis method is used to establish the overall space analysis model of whole bridge and to determine the most unfavorable load combination effect of arch springing node. The linear and nonlinear refining finite element analysis models of connection area of arch springing and pedestal are established. According to the comparison, the article studies the local stress distribution laws of three comparison schemes of arch springing transition section, and puts forward the reasonable construction scheme,which can be referred for the design and construction of the similar bridges.
