新型拉索转向器构造研究

Structural Analysis of New Type Cable Deviator

对于连杆承受拉力的张弦梁桥,在拉索采用平行钢绞线索体时,其转向器不能采用悬索桥索夹构造。基于某三叉张弦梁桥的拉索转向器受力需求,提出新型转向器构造设计方案,讨论其技术效果,计算结构受力性能。经过研究,关键指标均满足要求,相关成果已用于实桥。

In beam string bridge with linkage bearing tensile forces and cable using parallel strand structure,deviator scheme could not adopt the type of cable clamp of suspension bridge.This paper based on mechanical requirements of Y-beam string bridge,proposes structural scheme of a new type cable deviator,discusses technology effects and calculates structural forces states.After researches,key indexes of structure could meet design requirements,and those research achievements are used in real bridge.
