新滩大桥箱梁0#块施工支架方案的技术特点

The Technical Characteristic in the Construction Scheme of New-beach-bridge Box Girder 0#

新滩大桥箱梁0#块施工方案采用了薄壁墩侧面设置钢牛腿作为主要承力构件,且自行设计的组合截面钢箱梁和贝雷梁分别作为纵横向受力主梁的临时支撑结构体系。同时结合双薄壁墩的特点为保证结构安全采取了临时墩顶锚固措施,本文就此介绍在该箱梁0#块施工过程中的新技术新方法及其特点。

The new - beach - bridge box girder 0# adopted the construction scheme which setting the steel corbel on the thin wall pillar side as mainly holding component, contcmporarily using independently designed compound section steel box girder and Bchre beam separately as temporary supportting structure system for the vertically and horizontally stressing main girder. Also because of the consideration of safety, the construction scheme simultaneously adopted the temporary pillar to go against the anchor aimed at the construction scheme, this article will introduce the new technology, new method and characteristic of the new - beach - bridge box girdcr0#.
