Abstract：Research purposes: In the reconnaissances that the survey time is pressed，lots of works should be done，the mountain is steep and the geological condition is complicated，how to choose the suitable comprehensive geophysical prospecting method and to give its full play of rapid survey with big survey depth and how to develop the inversion technique that can reflect the abnormal data on the latent danger with high precision are crucial to enhancing the survey precision and effective overcoming the complicated geological condition．
Research conclusions: For the comprehensive geophysical prospecting for the long Taihangshan Tunnel，the comprehensive prospecting was used，obtaining rapid，economical and high efficient effects，the data processing and interpreting technologies were developed，getting the clear abnormal pictures． The 73 abnormal areas were found by conducting the comprehensive geophysical prospecting and it provided the basis for determining the unfavorable geological body and water － rich area and arranging deep boring． So the survey precision was much enhanced． In the rather high level，it shows the basic study is crucial to the development and progress of the geophysical prospecting，having good scientific sense．
