Abstract Porous media resistivity is affected by a number of factors. In the specific structure of the soil wall sites，changes in resistivity depend on the moisture and temperature changes. By the resistivity model analysis of rammed earth wall in Ruins of Jiaohe，combining with the improved Archie model，a resistivity model for the wall in a specific structure is established by the tests to find out the relation between water content and resistivity，and to determine the structural parameters and soil parameters in the model formula. According to the established formula by the moisture inversion with the resistivity，using high-density resistivity chromatography，the field wall in Ruins of Jiaohe is tested. The results demonstrate the practicality of the model formula in relics sites，which lays foundation for practical application of monitoring water translocation in relics sites.
