Locations and strikes of such main structures as faults and synclines in Zhangfang area were detected by using the method of Schlumberger electric sounding. Also, the distribution of Quaternary in the survey area was zoned based on the data from geophysical detection. The final results of drilling logs show that the method of electric sounding is quite powerful and effective in the exploitation of groundwater in mountain areas on condition that reasonable polar distances and profile directions are assigned.
