摘　　要：为减少施工过程对营业线的影响,现在跨铁路营业线桥梁施工中越来越普遍地采用转体法施工。而称重试验是转体施工中重要的一步,通过称重试验获得相关力学参数,为后续转体指挥决策提供依据。通过跨既有焦柳线铁路(56 m+56 m)T构桥梁转体施工称重试验施工实践,介绍了转体桥梁施工中称重试验的一般方法及原理,提出了相应配重方案的一般方法。In order to reduce the impact of the construction process on the business line,the use of the swivel method is becoming increasingly common in the construction of bridges across railway business lines.The weighing test is an important step in the rotation construction,and obtaining relevant mechanical parameters through the weighing test provides a basis for subsequent rotation command decisions.This paper introduces the general methods and principles of weighing tests during the construction of a(56 m+56 m)T-shaped bridge spanning the existing Jiaoliu Railway and proposes a general method for corresponding weighing schemes.
