悬索结构在输电线路大跨越工程中的应用初步研究

Preliminary research on suspended cable structure in large-spanpower transmission line engineering

悬索结构是一种高效率的结构体系,它能最合理的利用建筑材料的物理性能,从而节省结构所需的材料.本文借鉴桥梁工程中悬索桥的力学模型,初步研究了在大跨越输电线路中,采用悬索结构替代常规自立式铁塔的方案.计算结果表明,该结构体系可以大幅降低结构本体、基础、占地等工程造价技术经济指标.

The suspended-cable structure is a very efficient structural system;it could take advantage of the physical performance of architectural materials,accordingly saving materials.In this paper the mechanical model of suspended-cable bridge is studied for reference in order to put it to use in large-span power transmission line engineering.The study results,show the suspended-cable structure could largely reduce materials,foundation,occupied-land,cost of a project.
