大跨度桥梁钢箱梁吊装施工技术

Construction Technology for Hoisting Steel Box Girders of Large-span Bridges

大跨度复杂钢箱梁结构在吊装过程中常会因受力不均匀而开裂,且误选吊装工艺和起吊装置均会对大型钢箱梁结构的稳定性和使用寿命产生较大影响,因此结合实际工程研究大型钢箱梁结构的吊装技术至关重要。基于此,本文就结合某桥梁工程实例,详细论述大跨度桥梁钢箱梁吊装施工技术要点,旨在促使大跨度桥梁施工水平的不断提升。

Large span complex steel box girder structures often crack due to uneven stress during lifting,and the incorrect selection of lifting technology and lifting devices can have a significant impact on the stability and service life of large steel box girder structures.Therefore,it is crucial to study the lifting technology of large steel box girder structures in combination with practical engineering.Based on this,this article combines a bridge engineering example to discuss in detail the key points of steel box girder hoisting construction technology for large-span bridges,aiming to promote the continuous improvement of the construction level of large-span bridges.
