多跨斜拉桁架连续梁桥的设计与研究

Design and Research of Multi - span Continuous Stayed Truss Bridge

斜拉桁架桥在我国虽不乏成功的先例,但多跨斜拉桁架的设计尚不多见,本文通过对某5跨斜拉桁架连续梁桥的设计和分析,对多跨斜拉桁架的受力特点、施工工艺作了探讨,并揭示了一些基本规律,以期供今后类似的桥梁设计参考和借鉴。

Many successful examples about stayed truss bridge have been experienced in China, however, it' s rare to see design of multi - span stayed trusses. Based on design and research of one five - span continuous stayed truss bridge, this paper probes into force characteristic and construction craftsmanship of multi - span stayed truss and sums up some basic law, which will be very valuable for design of relevant bridges in the future.
