运梁河特大桥转体梁不平衡重称重试验分析

Re-weighing Test Analysis of Swivel Beam for Yunliang River Bridge

哈大客专运粮河特大桥跨既有线连续梁采用平转法施工,为确保转体顺利进行,转体前进行了T构不平衡重试验分析,文中介绍了一种转体构件不平衡重的测试方法和应用过程。结果表明,方法有效可行,可供同类工程借鉴。

Yunliang River Bridge use the horizontal swivel method for continuous beam construction which across the existing Harbin-Dalian passenger line. A re-weighing test and analysis is carried out to ensure the smooth swivel. This paper presents an unbalanced weight test method and application process. The results show that the method is effective and feasible, can pro- vide references for similar projects.
