劲性骨架在桥梁设计中的应用探讨

Discussion on application of stiff skeleton in bridge design

针对我国桥梁建设向大跨径方向的发展趋势,劲性骨架在各类桥梁结构体系中扮演着越来越重要的角色。本文着力于劲性骨架在连续梁桥、拱桥、斜拉桥中的广泛应用,重点阐述劲性骨架在大跨径桥梁合龙段、全桥设计以及斜拉桥塔结构中的作用。为劲性骨架在桥梁设计中的多元化、多方向的应用发展奠定一定的基础。

In view of the development trend of long-span bridge construction in China,stiff skeleton plays an increasingly important role in various bridge structure systems.This paper focuses on the wide application of rigid skeleton in continuous girder bridges,arch bridges and cable-stayed bridges.The role of rigid skeleton in the closure section,the whole bridge design and the pylon structure of long-span bridges is mainly expounded.It lays a solid foundation for the diversified and multi-directional application of stiffness skeleton in bridge design.
