Abstract：Research purposes: Taking the Nujiang River Bridge of the Dali － Ruili Railway and the Jinsha River Bridge of the Lijiang － Xianggelila Railway as examples，in the light of the principle of giving consideration to the exploration depth and the exploration expense，the study was done on the comprehensive geophysical exploration pattern for the bridge with high pier and big span under the complex geological condition in order to enhance the exploration precision．
Research conclusions: The comprehensive geophysical exploration patterns for the bridge with high pier and big span under complex geological condition are as follows: ( 1) The comprehensive geophysical exploration is conducted with the three levels of the exploration precision． ( 2) The selected geophysical methods include the audio magnetotelluric method ( CSAMT or AMT) ，shallow seismic reflection wave method，DC electric sounding or high density resistivity method，tomography on cross － hole elasticl wave method，tomography on cross － hole electromagnetic wave method and single －hole well logging method． ( 3) The attention should be paid to the location survey stage and the main pier position of the recommended plan．
