The invention discloses a determination method for detection results in a pulling-out method. The determination method includes: performing occlusion force test to obtain an occlusion force mold; collecting field test data of effective pre-stress under an anchor and anchor extension pulling force, and according to the collected data, drawing pulling-out method test characteristic curves; accordingto the different types of the pulling-out method test characteristic curves, performing prediction and determination of the effective pre-stress under anchor. The method is simple in practical operation and has convenience in recognition, can quickly and accurately determine whether a steel strand is qualified or not, thus improving detection efficiency and accuracy and improving engineering quality.
