某公路斜拉桥现浇箱梁挂篮方案比选分析

摘要:

主梁挂篮施工作为斜拉桥施工的关键环节之一,对该桥梁质量安全、工期、造价方面具有显著性影响。本文通过对牵索挂篮和组合式菱形挂篮施工方案进行技术、安全和经济性分析,论证后支点式菱形挂篮在宽幅斜拉桥主梁施工中的适用性,为类似工程提供参考和借鉴意义。

Abstract:

As one of the key links of cable-stayed bridge construction, the construction of main beam hanging basket has a significant impact on the quality and safety, construction period and cost of the bridge. Through the technical, safety and economic analysis of the construction scheme of the cable hanging basket and the combined lozenge hanging basket, this paper demonstrates the applicability of the rear support lozenge hanging basket in the construction of the main girder of the wide cable-stayed bridge, providing reference and reference significance for similar projects.
