摘要
文章依托来宾市永鑫大桥施工监控项目,提出采用压力传感器测试单根钢绞线张拉力的均匀性及采用频率法测试整索索力大小的监测方法,并对频率法测试拉索索力的影响因素进行了分析及修正。实际应用结果表明:该监测方法的测试精度较高,能够满足施工质量控制要求,可为该类结构的斜拉索索力监测工作提供参考。
Relying on Laibin Yongxin Bridge construction monitoring project,this article proposed the monito-ring method by using the pressure sensor to test the uniformity of single strand tensile force and using the frequency method to test the cable force size of entire cable,and analyzed and corrected the influencing fac-tors of cable force test by frequency method.The practical application results showed that：this monitoring method has the higher measurement accuracy,able to meet the requirements of construction quality control,thus it can provide the reference for cable force monitoring work of stay cables under similar structures.
