The on-line monitoring of power transmission line mainly refers to the observation of load parameters such as wind speed and ice coating thickness, and not many researches about monitoring and safety status are conducted directly targeting their stress states; however, through when calculating the stress status of structure via load, the simplified assumptions in calculation model and load model introduce some errors. This thesis realized real-time monitoring to stress states of main stress poles of iron tower based on the 36 strain monitoring points distributed on the power transmission iron tower; in addition, based on the analysis on monitoring data, this thesis evaluated the safe using performances of the iron tower.
