Abstract: Based on the resistivity imaging detection test of Earth-rock Dam Leakage passage，the arrangement affects the leakage passage inversion image in three different arrangements as follows: the inversion image of resistivity can reflect the range of leakage passage under three kinds of arrangement，and Wenner array inversion image is the best. But the three kinds of inversion image can not reflect accurately the location of the leakage passage.

Key words: earth-rock dam, model test, leakage passage, high density resistivity method, inversion

摘要： 通过对土石坝坝体渗漏通道的电阻率成像诊断试验，得出在3种不同排列方式情况下，排列方式对渗漏通道 反演结果的影响为:3种排列方式下电阻率成像的反图像都能够反应出渗漏通道的范围，其中温纳排列的反演图像 效果最好，但是3种反演图像都不能够准确反应出渗漏通道的位置。
