武汉市二环线武昌段接线工程梅家山立交桥钢箱梁项目属于既有交通线下高风险路段施工项目. 主线桥钢箱梁跨路施工过程中,采用现场情况分析、模型数据计算分析与试验测试等步骤,探索了既有交通线上钢箱梁顶推法施工工艺、临时工程设计布置等方法,形成了一套较为完整的钢箱梁连续顶推施工技术和安全操作技术要点. 运用该方法进行施工,桥下交通影响较小,施工干扰小,安全系数高. 确保了工程进度和施工质量,有效节约了施工成本.

The Meijiashan overpass steel box girder project at Wuchang section of Wuhan′s Second Ring Road is a high-risk road construction project on existing transportation line. Aimed at the across-road construction process of the main bridge steel box girder, the steel box girder pushing technology on existing traffic lines and the temporary engineering design layout were explored by analyzing the on-site situation, computing model data and test, the steel box girder jacking construction technology and the key points about safety operation were proposed. The practice proves that it has little effect on the traffic under the bridge and the construction process, which guarantees the project progress and the construction quality, and saves the construction cost.
