文章以某桁式组合拱桥为例,建立其新拱脚局部三维有限元模型,分析了该部位的应力分布特征,分析结果与桥梁病害调查情况吻合较好,最后对新拱脚局部设计提出了改进措施。
Taking a truss-type composite arch bridge as an example, the local three-dimensional finite element model of the new arch was established and the stress distribution characteristics of the arch were analyzed. The analysis results are in good agreement with the investigation of the bridge disease. Finally, improvement measures.
