| 摘 要： | 在实际结构中,由于施工过程中的制作、安装等因素,初始缺陷是不可避免的.通过施加不同大小和形式的初始几何缺陷来研究其对钢管混凝土拱桥极限承载力的影响,结果表明初始几何缺陷对承载力的影响是明显的,在实际工程中应予以重视.

| Abstract: | In real structure,initial defect can't be avoided because of facture and fixing factors.By applying different scale and different form initial geometry defects on calculation model,the defect effect to the ultimate bearing capacity of CFST arch bridges had been researched.The results showed initial geometry defects could affect ultimate bearing capacity obviously.The conclusion of this paper should be regarded in practical engineering. |

| Keywords: | concrete-filled steel tubular arch bridge ultimate bearing capacity initial geometry defect. |
