摘　　要：为适应交通运输发展的需要,上海市吴淞大桥北引桥需与新建的外环线同济路立交相接。为节约投资、加快工期及减少对周围环境的影响,决定屏弃拆桥重建的传统施工方法,而采用原桥利用(整体顶升)的施工法。对顶升方案、设备、技术、施工、注意事项及取得的效果等作了较详细的阐述。To cater for the development of communications and transportation, the north access of Shanghai Wusong Bridge is to be connected with the newly built Tongji grade separation of Outer Ring Line. To cut the cost, shorten the construction time and minimize the interference on surrounding environment, the conventional construction way of demolishing && rebuilding was abandoned, and the whole-body-jacking-up method is applied with the utilization of the existing bridge. Details are presented on jacking schemes, equipment, techniques, construction, key points and the results.
