摘　　要：提出了一种新型连续索滑移模型,利用现有有限元分析工具进行求解,容易实现且收敛性好,可以满足连续索在实际工程中的应用精度。根据这种连续索滑移模型,构建了索托结构模型,并将其与索两端锚固的斜拉结构进行各项力学性能对比,研究结果表明索托结构是一种高效的大跨结构形式。This paper presents a new continuous cable sliding model with the finite element method, which has good convergence and fulfils the precision of continuous cable applied in practical projects. Based on this cable sliding model, cable-held structures are studied and compared with cable-stayed structures in which cables are fixed at both ends. The results show that cable-held structures can be applied in large-span structures because of its excellent mechanical performance.
