摘　　要：在运用钢吊箱法进行桥梁承台施工时,要结合现场情况进行科学设计,包括计算水、土、混凝土的压力,明确钢吊箱的起吊位置和尺寸规格等。在具体施工时,还要重点把握拼装下沉、套箱封底、承台与墩身施工等技术要点。只有统筹做好方案设计和加强施工管理,才能确保高速公路桥梁工程的使用安全。In the construction of bridge cap by steel hanging box method,scientific design should be carried out according to the field conditions,including calculating the pressure of water,soil and concrete,defining the lifting position and size specification of steel hanging box,etc.In the concrete construction,we should focus on the assembly sinking,casing bottom,cap and pier construction and other technical points.Only by doing a good job of project design and strengthening construction management can we ensure the safety of highway bridge engineering.
