Research conclusions:(1)Data collection:The difference of data collection for geophysical exploration between Lhasa to Linzhi section and general areas is very big，geophysical workers face the great difficulties such as environment of hypoxia，low temperature along the steep terrain，a footraee with heavy armor, instruments and supplies of tunnel ground walking. Therefore in the steep terrain and extremely difficult location where the ground elevation is more than 4 500 m， the existing system of logistics supplies condition cannot ensure the safety of the personnel, it is difficult to collect the geophysical data，so there would be a lot of data blank. ( 2)Data processing and interpretation:There is no difference between Lhasa to Linzhi section and general areas.(3)In the inverted resistivity profile，the positions where low resistivity of strip that goes downward is abnormal or there is gradient high value correspond to the suture zone. ( 4)The research results can be used for other alpine region on engineering geophysical exploration.
