	为了了解截面填充率对部分填充钢箱–混凝土拱受力性能的影响，本文利用ABAQUS有限元软件建立部分填充钢箱–混凝土拱的数值模型，分析了截面填充率对该类结构受力特性的影响。分析结果表明：对称加载时的极限承载力明显要大于非对称加载时的极限承载力；极限荷载随着截面率的增大而提高；填充率对拱结构的刚度和破坏形态影响不大，但其延性随填充率的增大而降低。本文所获得分析成果可为该类结构的进一步研究及工程应用提供参考。<br />
In order to understand the effect of section filling rate on the mechanical properties of partially filled steel box-concrete arches, this paper uses ABAQUS finite element software to establish a numerical model of partially filled steel box-concrete arches, and analyzes the effect of section filling rate on the mechanical properties of this type of structure influences. The analysis results show that the ultimate bearing capacity under symmetric loading is obviously greater than that under asymmetric loading; the ultimate load increases with the increase of the section ratio; the filling ratio has little effect on the stiffness and failure mode of the arch structure, but its ductility decreases with increasing filling rate. The analysis results obtained in this paper can provide references for further research and engineering applications of this type of structure.
