The invention discloses a method and a system for judging the time and temperature effect correction of the pull-out test result. By performing the temperature effect and the pre-stress change test under the time effect, a typical curve of the effective pre-stress under the anchor with time and temperature effect is drawn. The influence rule of temperature on prestress under anchor is analyzed, and the influence of temperature is eliminated. The variation of prestress under anchor with time is analyzed. A mathematical regression model of effective prestress unde anchor under that influence oftemperature effect and time effect is obtain by data fitting regression of the temperature-corrected test curve. It can quickly and accurately determine whether the stranded wire is qualified, which is conducive to improve the detection efficiency and accuracy of the prestressed stranded wire, give full play to the material efficiency, good economy, and also improve the engineering quality of theactual bridge.
