本文以某桁式组合拱桥加固工程为例,建立空实腹交接处(俗称虎口)局部实体有限元模型。首先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。其次,针对虎口处出现的病害提出的加固措施进行了计算分析比较,最后得出虎口处有效的加固处理措施,为同类桥梁相似病害的加固提供一定的参考。
In this paper, a truss composite arch bridge reinforcement project as an example, the establishment of empty real belly junction (commonly known as tiger mouth) local solid finite element model. Firstly, the stress distribution characteristics of this part are analyzed. The analysis result is in good agreement with the investigation of the bridge disease. Secondly, the reinforcement measures proposed for the diseases appearing in the tiger’s mouth are calculated and analyzed, and finally the effective reinforcement measures are obtained for the tiger’s mouth to provide some reference for the reinforcement of the similar diseases of similar bridges.
