摘要
实践证明,钢箱梁斜拉桥采用顶推法施工时,不需大型浮吊等起吊设备,占用场地小,钢箱梁顶推、边跨支架梁段安装和塔柱的施工可同时进行,提高施工效率,节约成本,充分显示了本桥施工方法的合理性、先进性与独创性。
The practice proves that in construction of the steel box girder cable-stayed bridge using incremental launching method, we don＇ t need large floating cranes and other lifting equipment. For the occupied space is small, the construction of steel box girder incremental launching, edge across stents beam section and pillar can be conducted simultaneously which improve the construction efficiency, save the cost, show the reasonableness, advanced and originality of the bridge construction methods.
