摘　　要：柳州三门江大桥主桥为(100+160+100)m双塔双索面三跨部分斜拉预应力混凝土箱梁桥,桥面宽41m,居同类型桥梁国内第一。文章介绍了该桥悬臂施工中采用的控制方法和施工控制主要内容,重点介绍了施工过程中主梁变形、斜拉索索力的测试和控制及主梁截面应力、索塔变形的监测。工程实践表明,该施工控制方法合理,取得了满意的控制效果,为同类型桥梁的施工控制提供了参考。The main bridge of Sanmenjiang Bridge in Liuzhou City, 100＋160＋100m in length and 41m in width, is of a 3-span partial cable-stayed prestressed concrete box beam structure with two pylons and double cable planes, which ranks first among the similar bridges in China. The paper introduces the controlling methods and the main controlling contents for cantilever construction, and mainly introduces the test and control of the girder deformation and the cable force, the surveillance of the grider section Stress and pylon deformation. The engineering practice proves that the controlling method is reasonable and achieved satisfactory results and can be consulted by the construction of similar bridges.
