大跨度桥梁钢箱梁顶推施工的控制与监测

Control and Monitoring of Steel Box Girder Pushing Construction of Long-span Bridges

大跨度桥梁多采用钢箱梁结构,其具有轻质、高强、施工周期短等特点。钢箱梁施工一般采用吊装、顶推或两者相结合的施工方法,介绍了顶推施工时对钢箱梁实施的施工控制及监测的主要内容及原理。

Steel box girder structure is widely used in long-span bridges, which has the characteristics of light weight, high strength and short construction period. The construction of steel box girder usually adopts the construction method of hoisting, pushing or combination of both. The main contents and principles of construction control and monitoring of steel box girder during pushing construction are introduced.
