Abstract：
The pre-tensile force loss of high strength bolts analyzed using orthogonal test, under the four factors of the final twist time, bolt diameter, linking slab thickness and environmental temperature at three levels. The proper order of influence factors considered in this paper, from big to small, was the final twist time, bolt diameter, linking slab thickness and environmental temperature. Meanwhile, two groups were tested by the single factor of long time and the changing regularity of pre-tensile force loss was obtained.
