大型钢箱梁吊装施工工艺在跨金马河大桥工程中的应用

Application of Hoisting and Installation Technology for Large Steel Box Girder in Bridge Project Cross Jinma River

随着我国钢铁工业产业的迅猛发展,钢结构施工技术也在不断优化完善。在此背景下,钢结构桥梁在路桥建设工程中得到了广泛的应用,促使大跨度钢箱梁出现在全国各地的桥梁工程中。以跨金马河大桥建设工程作为研究案例,对钢箱梁吊装施工工艺展开深入、全面的研究分析,列举出钢箱梁吊装作业时常用的方法。

With the rapid development of steel industry in China, the construction technology of steel structure is constantly optimized and perfected. Under this background, steel structure bridge has been widely used in road and bridge construction projects, prompting the emergence of large-span steel box girder all over the country. Taking the construction project of bridge cross Jinma River as a case study,this paper conducts a thorough and comprehensive research and analysis on the hoisting construction technology of steel box girder, lists several methods often used in the hoisting operation of steel box girder.
