摘要
比较分析了粘贴应变片法和弦振频率法在系杆内力监测中的应用情况,并根据实测数据对系杆管道磨阻系数进行调整,减少其和实际测试结果的偏差。结果表明根据本文方法系杆张拉力控制达到了施工要求。
In view of the conventional measurement in tie bar internal force, wire vibrating frequency measuring method and strain pieces measuring method for pipe fraction factor are compared. According to measured data, pipe fraction factor was adjusted to make the measurement more reasonable and accurate. The results show that the tie-bar internal force monitoring and controlling based on this method can reach the stranded,which providing a reference for similar circumstance.
