摘要
以一座下承式钢箱系杆拱桥为研究对象,采用大型有限元软件ANSYS建立拱脚的局部有限元模型,分析其最不利荷载工况下的应力分布及传力特征,对拱脚的构造的合理性作出综合评价。
With a through steel box tied arch bridge as the research object, local finite element model of the arch footing using large finite element software ANSYS is established. Stress distribution and transmission chara- cteristics is analyzed under the most unfavorable load cases. Making a comprehensive evaluation on the ratio - nality of arch foot structure.
