从钢管混凝土拱桥的发展现状及拱桥的特点与类型入手,阐述了钢管混凝土拱桥拱座研究现状与存在的问题,指出在进行钢管混凝土拱桥具体桥梁设计时,应结合现行桥梁设计规范对钢管混凝土拱桥进行整体设计计算和验算,然后选取拱脚结点的局部应力进行专门的分析,同时对比分析不同强度等级的混凝土拱座模型的应力,以确保结构的耐久性和安全性。
Based on the current situation of the CFST arch bridge and the characteristics and types of the CFST arch bridge, the research status and existing problems of the CFST arch abutment are described. It is pointed out that in the design of the CFST arch bridge, the CFST arch bridge The overall design calculation and checking are carried out. Then, the local stress of the arch foot joints is selected for the special analysis, and the stress of the concrete arch model with different strength grades is compared and analyzed to ensure the durability and safety of the structure.
