摘要
主梁挂篮施工作为斜拉桥施工的关键环节之一,对桥梁质量安全、工期、造价等具有显著性影响。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。
As one of the key links of cable-stayed bridge construction,the form traveler construction of main girder has a significant impact on the quality safety,construction period and engineering cost of the bridge.Taking the bent cap of viaduct in the main urban line of a project as an example,the construction schemes of the cable form traveler and the combined diamond form traveler are analyzed from the technology,safety and economy to demonstrate the feasibility of the rear fulcrum diamond form traveler in the construction of the main girder of wide cable-stayed bridge,which can be referred for the similar projects.
