摘要
采用磁通传感器对甬台温铁路温州站站房的体外预应力索进行了施工阶段测试,测试结果表明:单根张拉群锚预应力筋时,需考虑锚口摩擦损失的影响,可采用超张拉至1.03σcon的工艺。
The paper makes test on the tension construction of the external prestressed cables of the Wenzhou station buildings on the Ningbo-Taizhou-Wenzhou Railway by the magnetic flux transducer.The test result displays that the technology beyond the tension to 1.03σcon can be used with regard to the influence of the loss due to friction on anchorage mouth when face to the single cable tensioned prestressed group anchorage.
