中文摘要:
      石家庄西柏坡高速公路田家庄互通立交跨越京广铁路货迁线,为一联2×67 m双幅曲线预应力混凝土T型刚构结构,采用同步转体施工方案,为保证转体工序的顺利进行,转体前应采取措施使T 构在两个方向达到平衡。为此,确定其是否平衡的称重试验和试转工作是必不缺少的。介绍了该桥称重试验的原理主要内容及步骤,介绍了称重试验中数据处理的方法,并对试验结果进行了分析,提出T构平衡配重的方案,工程结果显示效果良好。
英文摘要:
      Tianjiazhuang freeway interchange bridge of Shijiazhuang Xibaipo highway consists of a group of 2 × 67 m double amplitude curve pre stressed concrete T shape rigid frame across Beijing Guangzhou cargo railway. This bridge was constructed by the synchronous swivel scheme. In order to ensure the smooth progress of construction process, some measures were taken to make T structures balance in two direction before swivel, so the work of determining the weight balance of the T rigid frame and trial rotation is indispensable. This paper introduces the basic principle, main content and weighing test steps of the bridge, introduces the processing methods of test data, analyzes test results, and puts forward the balance weight scheme of the curve T shape rigid frame bridge.
