摘　　要：随着现代化的发展,钢箱拱桥也越来越多的出现在跨江河中。针对跨河钢箱拱桥的施工,通过对揭阳某特大桥水中浮吊吊装大节段钢箱拱肋进行施工技术研究,解决了运输船横向停靠难度大,大型浮吊精准移位困难,拱肋安装精度难以调整,水中支架设计用钢量大,稳定性难以保证等难题,为后续浮吊吊装大节段拱肋提供了技术参考和施工指导,保证施工安全。With the development of modernization,more and more steel box arch bridges appear across rivers.In view of the construction of a river-crossing steel box arch bridge,studies the construction technology of floating crane hoisting and installing large-section steel box arch rib in the water of an extra-large bridge in Jieyang,it is difficult to adjust the installation precision of arch rib,use large amount of steel in the design of underwater support,and ensure the stability of arch rib.
