During the construction of the Qinghai-Tibet Railway, the perpetually frozen ground constitutes a key problem. The geophysical exploration will meet more complex and changeable objects in the perpetually frozen ground area than in the non-frozen area. Hence, the selection of rational working methods seems to be especially important. Based on a discussion on the strong and weak points of various currently-used geophysical techniques, the author advances the idea of integrated geophysical exploration with the enumeration of some practical examples. Practice shows that the integrated geophysical exploration is an effective means in the exploration of perpetually frozen ground.
