摘　　要：国产高钒光面索应用于大跨度空间结构始自于乐清市体育中心“一场两馆”项目,其索力值大小是结构安全的控制性要素.本文基于乐清体育中心体育馆项目,针对国内首次采用的非密封高钒光面索的索力监测问题,开展了系列1∶1足尺试验研究.研究基于磁通量方法进行此类索索力监测的可行性,并进行了充放电压、线缆长度、传感器位置、索体直径大小等因素对监测结果的影响规律研究.本文工作将为基于磁通量方法的拉索索力监测工作提供有益参考.The application of domestic non-enclosed GALFAN smooth surface cables to large-span spatial structures began in the"one stadium and two gymnasiums"projects of Yueqing Sports Center.The cable force value is a controlling factor of structural safety.The magnetic flux method for cable force monitoring is currently one of the commonly used methods for cable force monitoring.In this paper,a series of 1:1 full scale comparative experimental studies have been carried out on the cable force monitoring of non-closed GALFAN smooth surface cables based on magnetic flux method,which is used for the first time in China.The feasibility of magnetic flux method for the cable force monitoring of this type of cables is studied,and the influence of the related factors such as charging and discharging voltage,cable length,sensor location,cable diameter and other factors on the monitoring results is studied.This work will provide a useful reference for the application of magnetic flux method in monitoring cable force.
