Abstract：The bolt wedge load test and nut ensure load test were introduced，the method of combining the two tests and there liability of test results were discussed. When combining the two tests，although the wedge cushion made the upper part of the bolt under a bending load，the force direction of the nut was not changed while the nut was keeping ensure load.The nut load with15 s had no effect on the maximum tension load under the wedge load of the bolt. The combined test not only improved the test efficiency and the reliability of test results，but also truly reflected the use environment of the bolt connecting pair.
